I imagine when you swap from 6 volt to 12 volt, you will also swap from + ground to - ground. I have read on the internet, so we know it must be true. The used 6 volt coil is use to being ran in one direction, when you swap the + ground to - and juice flows in the opposite direction, you might get some strange issues. Intermittent missing in a certain rpm range etc... Coils are cheap enough, buy a new one and eliminate possible future problems chasing down weird issues, save the old one for a spare to get you home or test something else. I suggest you save the old 6 volt coil, build another B series truck around it Yes, I'm swapping to negative ground as well. I'm not saying I'm stuck on a 6-volt coil, that was just my first thought when I decided to convert. Mounting a resistor is not something I was looking forward to as it would just look out of place. Of course everything you read on the internet is true! I can't imagine anyone placing false information out there...... ? As far as building another B series around the 6-volt coil that sounds like the radiator cap syndrome. Remove radiator cap, drive new vehicle under radiator cap and reinstall radiator cap I will just about guarantee this truck will be my last. I'm also in the midst of restoring a 1972 Triumph TR6 and an a 1974 Airstream Argosy 20' motorhome. Both are money pits that put this truck to shame as far as cost are concerned! All while drawing really close to retirement. Brad Quote Link to comment Share on other sites More sharing options...

You can buy a 12 volt coil with built in resistor so you do not need it. I get my opinion from reading the H.A.M.B. there was a trouble shooting session going on about a strange miss. In the end it was the guy switched from 6 volt to 12 volt and a new 12 volt coil fixed him up. I can not say you will find the same issue, but it might be something to think about and just avoid. 10 minutes ago, bkahler said: As far as building another B series around the 6-volt coil that sounds like the radiator cap syndrome.

Yeah, finding a 12 volt coil shouldn't be to difficult. Just need to find one with the right mounting bracket. 21 minutes ago, Los_Control said: I get my opinion from reading the H.A.M.B. there was a trouble shooting session going on about a strange miss.

Radarsonwheels Posted November 7, 2019 Report Share Posted November 7, 2019 I have had luck with the MSD blaster II coils- the red canister type. They fit right in stock mopar strap brackets Quote Link to comment Share on other sites More sharing options...
bkahler Posted November 9, 2019 Author Report Share Posted November 9, 2019 I think I'm going to initially try a 1.4 ohm resistor with the stock coil. I really like the look of the stock coil, and probably more important, I've already restored the original coil! I'll probably mount the resistor under the dash where it will be out of sight.

bkahler Posted November 10, 2019 Author Report Share Posted November 10, 2019 The last few days I've been trying to figure out my shock situation. The oem parts manual indicates all four shocks should be the same so I ordered four monroe 31000 shocks as suggested by several threads. They weren't even close. Mounting id was wrong (5/8 instead of 11/16) and they weren't even close to the right length on the fronts. So that got me looking closer at my truck. The rears have an at rest length of 16-1/4" and the fronts are 19" at rest. Not even close to being the same! It appears the recommended Gabriel 82065 shocks will work on the rears. Now I have to figure what to use on the front. My truck is totally stock so I'm baffled why they are different when the book says they should be the same.

JBNeal Posted November 10, 2019 Report Share Posted November 10, 2019 Since ya asked nicely and we had a nice break in the weather and I had some free time between disasters, I did some tedious engineering work and was able to clarify an issue regarding shock absorbers...I suggest returning the 31000 shocks and order 66858 shocks Quote Link to comment Share on other sites More sharing options...

JBNeal Posted November 11, 2019 Report Share Posted November 11, 2019 (edited) From the Monroe website: 66858 collapsed/extended: 12"/19.25" 66858 bushing ID/width: .69"/1.56" 31000 collapsed/extended: 12"/19.5" 31000 bushing ID/width: .63"/1.25" 32207 collapsed/extended: 11.25"/17.88" 32207 bushing ID/width: .63"/1.25" When I picked up the 31000 and 32207 shocks back in '98, the parts guy went to his big parts book and had these on the shelf (!)...when I pulled the original shocks off of the '49 back in '04, I compared them to new 31000 and 32207, and they were the same in all critical dimensions. The parts book says that the B-3-B has 4 shocks (p# 1321268), so I'm thinking the Dodge engineers figured the suspension travel limits were within the specs of the 31000...they increased the shock mount stud diameters for increased shear strength, and Bob's yer uncle, the new 66858 fits the bill on all 4 corners Edited December 9, 2019 by JBNeal updated info 1 Quote Link to comment Share on other sites More sharing options...
bkahler Posted November 11, 2019 Author Report Share Posted November 11, 2019 Ok, I found a reasonable deal on ebay for $35 each and ordered four. Amazon wanted $44 each so I figured I'd try and save a few bucks going the ebay route ? So it looks like my truck will have shocks early next week. Thanks for the info!

JBNeal Posted November 11, 2019 Report Share Posted November 11, 2019 that is a great deal...before I dug this up, my cursory research was finding shocks for $75 EACH on no-name brands...that's kinda pricey even for struts on a fully independent suspension...I need to reach out to Monroe, RockAuto, Roberts etc to let them know this application, if anyone will listen...

bkahler Posted November 11, 2019 Author Report Share Posted November 11, 2019 More tinkering this weekend. Got the firewall panel installed this weekend. I bought it from Roberts about 20 years ago. The quality is so so but it did fit for the most part. I suppose the worst part was they miss located the hole for the starter pedal and I had to cut about 1/2" out of the bottom curve to make it fit. All but one of the button holes were located correctly. Fortunately I had the remnants of the old panel which helped me locate the holes for the heater, parking brake and wiring harness. Only had to use a small portion of my four letter word library during the install. Brad 1 Quote Link to comment Share on other sites More sharing options...
bkahler Posted November 11, 2019 Author Report Share Posted November 11, 2019 (edited) Oh yeah one other thing. I noticed last night that I apparently have the rear brake backing plates swapped. I have the drives side on the passenger side and vise versa. Another indication I was in a real hurry to get the truck on wheels so I could get it loaded on the trailer for the move south!

My 46 was that way when I got it. It's possible I have the hubs on the wrong sides as well but I know for certain that my backing plates are wrong because the brake lines to the rear wheel cylinders are angled to the rear and not the front. Considering that it's been 20 years since I assembled the brakes and suspension I've made the decision to just tear all of it apart, check things out and reassemble in the proper order. Better to do it all now while the access is nice and easy. At least I shouldn't have to deal with rusty bolts.....! Brad 1 Quote Link to comment Share on other sites More sharing options...
bkahler Posted November 12, 2019 Author Report Share Posted November 12, 2019 Back in 1997 when I was prepping the frame and various other components I came across a product called Copy Cad from Caswell Inc. It was advertised as a DIY product. I thought it sounded pretty cool and decided to try using it. In the attached picture are four J bolts that are used to fasten the rear leaf spring bumper mounts to the frame. I followed the instructions, sandblasted the parts, ect and they looked pretty good when I installed them. However, 20+ years later they don't look so good. I bolted them to the frame in 97 and the truck has always sat inside, never been wet. I would have to say the long term results are less than satisfactory. This time around I'm just going to sandblast and paint them black. Brad Quote Link to comment Share on other sites More sharing options...
bkahler Posted November 13, 2019 Author Report Share Posted November 13, 2019 Questions, questions and more questions 1) It appears I might have an issue with my heat riser spring. I'm not sure but it seems to operate backwards. Searching the forums it sounds like at one time Andy Bernbaum was selling some that were wound backwards. I bought my spring from Andy back in 1998. In order to be sure, what should the spring do when wind or unwind when heated? 2) It also seems that I have lost the spacer that goes on the shaft of the heat riser. Anyone know of a source for one? 3) Brake backing plate shims for shimming to create the correct clearances for the axles. Anyone know of a source for them? 4) I'm considering a dual horn setup. Anyone know of a source for a short version of the factory horn? 5) When installing the brake switch and the 1/4" plug in the back of the master cylinder, should I use any kind of sealant on those threads? Told you I had questions! Thanks, Brad Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted November 13, 2019 Report Share Posted November 13, 2019 1) It appears I might have an issue with my heat riser spring. I'm not sure but it seems to operate backwards. Searching the forums it sounds like at one time Andy Bernbaum was selling some that were wound backwards. I bought my spring from Andy back in 1998. In order to be sure, what should the spring do when wind or unwind when heated? The spring should hold the counterweight at the 12:00(ish) position. Exhaust flow across the internal flap wants to rotate the counterweight clockwise to the 3:00 position. As the spring heats up it should relax and allow the weight to stay in the 3:00 position. 2) It also seems that I have lost the spacer that goes on the shaft of the heat riser. Anyone know of a source for one? What spacer? Are you referring to the little arm with a cushion on the end? 3) Brake backing plate shims for shimming to create the correct clearances for the axles. Anyone know of a source for them? No known shims for purchase that I am aware of. You will either need to get some from another axle or make some out of shim stock 4) I'm considering a dual horn setup. Anyone know of a source for a short version of the factory horn? I found mine at a swap meet. 5) When installing the brake switch and the 1/4" plug in the back of the master cylinder, should I use any kind of sealant on those threads? Yes. Use some pipe thread sealant. I wouldn't recommend Teflon tape here as little pieces could get into the system. Stick with a paste sealer on the threads.

I'll tinker some more with it in the next couple of days (if the garage isn't to cold!). So the spring gets weaker and allows the weight to move down as the engine heats up. 7 minutes ago, Merle Coggins said: 2) It also seems that I have lost the spacer that goes on the shaft of the heat riser.

Merle Coggins Posted November 13, 2019 Report Share Posted November 13, 2019 It's been too long since I've had mine apart so I don't recall if I had that spacer or not. I assume it's just there to keep the spring in alignment, or to keep it from sliding back and forth. If you need something for that maybe a small washer would do the job.

JBNeal Posted November 14, 2019 Report Share Posted November 14, 2019 #3 spacer keeps the spring off of the manifold...a flat washer or piece of aluminum could be substituted...I won't tell anybody if you won't... The dual horn setup I found was purely by accident 8 years ago...answering a CL ad, I crossed the border into Oklahoma and headed to Kingfisher to go look at a '49 1-ton, then was told it was actually in Hennessy, then was told it was at a wrecking yard north of town...the truck was in much worse shape than advertised, and for the $$$ he wanted, I expected to drive it back across the border with a warm bucket of chicken by my side...we came to an agreement that I could buy as many parts as I could pull off of it before they fed it into the crusher 100 feet away, so I had to hustle to get little stuff of that hulk...them turkeys didn't even wait for me to crawl out of that filthy cab before the big loader started scooping it up...and they mashed that thing into a brick right in front of me, like they enjoyed it...it had salvageable stainless grill bars, fenders, doors, even the cab was ok (still had the corner glass in it)...se la vie, I reckon...so ya might be able to find an example with less drama involved on eBay Quote Link to comment Share on other sites More sharing options...
ggdad1951 Posted November 14, 2019 Report Share Posted November 14, 2019 You can always test the spring function with a torch, gently heating the spring to check its action/reaction. Quote Link to comment Share on other sites More sharing options...

That's my plan, using a propane torch. (If I can find it!) My assumption is the spring relaxes, i.e gets weaker, which allows the weight to fall.
