    Your photos are not coming up for me.  Does due diligence mean you have bore and strike measurements?  Stroke can be measured using the little plug over #6 cyl and a long dowel if the engine will rotate.  Bore will require head removal.

    No photos here either.   You should be able to tell the engine displacement by stroke alone, assuming the head measures 25 1/2 inches as the variations of that engine had stroke lengths unique to the long block.   At least that's what my quick look of the Motors data says.

  2. In addition to the pump, it will help to provide a vacuum 'storage' container.   Storage in quotes because it seems silly to store nothing!   Anyway , a vacuum storage can can be found on several older vehicles on the brake system, or make one from a piece of large PVC pipe, two caps and a couple of fittings.   Most PVC caps are thick enough to drill and tap for small pipe threads.  Add a one way check valve to the line.   This will even help a single pump equipped engine run vacuum wipers.

  3. Anti-seize compound on the hub/wheel centers and light coat on the wheel to hub meeting surface for me.   Some recommend on the threads too, and I've done that, but you need to modify the torque specs with such well lubed threads.   Might break a stud or bolt.

    It lasts much better that oil, and is intended for that use.

    There's a small port in the master that let's fluid return to the reservoir.  I suspect it's plugged or restricted at the least.  Binding at the pedal pivot may also be part of it.

    My guess also.   Pedal must fully return after each application.   Springs, binding or push rod adjusment are likely causes.

    Powerflyte 2 speed automatic?

    I think so too, as that seems to be the torque converter laying to the left of the trans, with the hub pointing up open to the elements.  Those are really good 2 spd transmissions and a much better converter that the others.

  6. There is also another ''scrub' term that is even more important IMO.   Scrub radius,  the arc the wheel area in contact with the road describes when turned off straight ahead.

     

    It's primarily influenced by kingpin inclination and a vertical line through the center of the tire.   Ideally the tire would rotate around a single point.   Very few modified vehicles do though.   Wheel offset and tire diameter can change that.

     

    From past experience I can tell you with certainty,  a large scrub radius really messes with the driving feel and tire wear.

    Just remember in the stock configuration the centering ring on the stock Hub is what centers the wheel. I would modify the rotor to fit properly if it were up to me. 

    Yeah, I'll probably do that, even though Toyota has used lug centric wheels with a fair amount of success.     But that requires right and tight specs during wheel manufacture.

    In my mind, the hardest part for DIY is the hub. Once you have that all you need to do is put a rotor on it and a caliper. If you pressurize the caliper, it will locate for you. Point the bleed up in a location that doesn't hit anything, then make a mounting plate to hold it there. I would def do it in steel, but I've never seen one that wasn't a flat plate.

    I think my original hubs will work with the Explorer rotor with a tiny bit of lathe work on the pilot hole and/or the hub register.   I do have a nephew with a machine shop that can do that for me, or if  I can talk the local auto parts place into it, that could be done on a regular brake lathe. 

     

    Several of the kit mounting plates I've seen in pics have short tubing spacers welded on to locate it laterally.  I won't know for sure what's needed until I mock it up with a plywood plate.

  9. Dad always kept a normal cluster shaft, cut to the correct length for common trans.   He ground a short taper on each end to aid in starting it.  In those days is was the 55-64 Chevy and Ford 3spds.   use it to drive out the installed shaft and use the 'real' one to drive out the dummy.   Or, since he did this almost every  day , he could just fill the gear with needles and lots of sticky wheel bearing grease and put it together    I used the cheat shaft.

    nothing wrong with striking out with another approach...before you start working this in metal why not mock it up in wood to check if this combination of components will work for the task at hand and if so, you basically have your template and wood is so much quicker and easier for mock up

    Yes, I plan on it.

  11. Thinking of fabbing my own brackets but I'm conflicted as to material dimensions and actual material.

     

    I can weld and grind steel but really accurate cuts or shaping is difficult without a mill.

     

    It would be nice to use aluminum as I lack steel machining equipment in my shop but could cut and shape aluminum accurately with my woodworking equipment.

    I've cut 1" plate on my table saw a few times and 1/4" a lot.   Router and shaper also work well at lower speeds and really rigid hold downs.

    The only issue would be welding if spacers need to be tacked on.

     

     

    I think steel brackets are normally 1/4, 5/16 or 3/8" thick.  Is that what those of you that have purchased them have seen?

     

    Thinking of 3/8 aluminum, 6061 as it is strong/rigid, readily available and not too expensive.

     

    Comments?

     

    I have a pair of Explorer disks that I think will work.  These are just for fitting as I saved them from a brake job I did.   If their size works out I'll get new ones.   Also have a pair of calipers, near new from a Mitsubishi truck.  They are nice and compact and have nice mounting arrangements.   Should be good for the application as Mits used two of each on each front wheel to stop a truck that was 14K loaded.  I'll be using one per side.

    The only way I can see oil getting there, is if the spark plug gasket is leaking?

    Many years ago they used to sell the washer/gaskets over the counter ..... Today seems they are all machined fit and no more washers.

     

    I can imagine if there was some blow by in that cylinder, it might be possible a small teeny tiny amount of oil is getting past the plug .... along with compression.

    Then as you drive it, will add up to enough oil to dab up with a rag.

     

    I certainly would suggest doing a compression check on the engine. See if that cylinder is lower then the rest and suggesting blow by.

     

    I wonder if there is some place on the internet that can order those gaskets?

    May not be the issue at all .... I wonder if you can clean it out then add a little water and run the engine. See if you can see little air bubbles coming out from escaping compression?

    Yep, they are available in a lot of places.   But, you can anneal the old ones to soften them and they'll seal better.

  13. I've seen a lot of old pickups with clamp-on trailer hitches, back in the day.   Anyone else remember those?   A couple of shaped steel plates attached with bolts clamping bumper in the middle?

     

    I remember day towing a fair load of railroad timbers with a 49 Plymouth with one of those.   Building fence at a newly purchased farm and needed to 'git ur done', and that's what he had.

  14. I also have never seen tow ratings.   When I get mine on the road I'll be guided by the GVW.  Since I don't have a GCVW available I'll add a few pounds and stop there.  

     

    The fluid couplings may be the biggest issue, other that HP and overall weight.   They have a fair amount of slippage designed in, far more than modern torque converters.   That slippage will create heat in the oil.   Probably not an issue for short periods but then longer it's operated the hotter it will get.

    I had the same thing after I had a engine rebuilt.  I looked every where for a leak, a oil trail nothing.  I attached my post from here the solution was not the solution.  I was at a car show at my  church and my rebuilder walked by.  I showed him the oil in my plug well.  He ah just put some "Stop Leak" in there.  That was four or five years ago the oil leak went away.  Until that time I was firmly against additives like that. 

     

     

     

    Stop leak in the radiator to stop an oil leak?   How does that work?   Or was it not oil?

     

    I'm guessing it was coolant leaking from a head bolt that did not have sealant on the threads.   Then the engine heat cooked away everything but the glycol.   Then it looks, smells and taste different than when it went into the radiator.   Am I close???

  16. OK, I'll give my 2cents on the trans oil discussion.   IMO it all depends on the condition or the synchronizers themselves.    Good, tight, little wear, good grooves in the contacting faces, those would get ATF in my trans.    More wear, may require something closer to the original.

     

    I base this on the factory recommendation from around the mid 60s.   The A833 in my 65 Dart came with Type A from the factory, as did most. There where a few complaints of a gear rattle in neutral from some owners so Mopar suggested a change to 80w90 for those only.  

     

    That little Dart was the best shifting standard trans I've ever driven.   That's why the one waiting to go in my 56 pickup already has ATF in it.

    I am talking about the pumpkin housing.  Sorry for the confusion.  The 3.54 pumpkin I got is from a 1956 V8 Desoto.  

    I replied to your PM.  My old Hollander is kind of spotty in coverage of pre 50 Mopar stuff.   But as best I can tell the V8s may be different.   Sixes seem to be the same from 50 on.   Probably earlier to but it doesn't cover them.

  18. Most of the 'pumpkin's will interchange.  I seem to recall that one can count the  studs/nuts attaching it to the housing and if they are the same, they interchange.  The axle spline count may be different but that can be remedied by changing axle gears in the dif.

     

    Changing the pumpkin and/or changing the axle gears require any gear setup.   Simple unbolt and reverse to install.

     

    I'm confused with the 'housings don't match' comment.   If you mean whole housing that icncludes the axles and center section, that isn't an issue if you're only swapping the pumpkin.   If you mean the pumpkin housing, I doubt that the internal gears will interchange if the casting is different.

     

    If you can provide the source of the replacement, I can look up the ring and pinion interchange in my old Hollander to determine for sure.
