  1. Yes, there are a lot of old cars and some not so old that have been worked on by un-knowledgeable mechanics, which could make them unsafe. Brake shoes will wear in eventually, but that could take several thousand miles. Vehicles with front drum brakes can be especially unsafe if not assembled / arced properly causing them to grab and could pull the vehicle to one side in a panic stop. Rear drum not done properly can cause safety concerns as well, but I believe not quite as critical as the front. We sometimes forget that automotive brake systems were / are highly engineered. Anytime we change t
  2. Besides the proper fitting, the material has a definite effect. Even in the old days when linings were full of asbestos, they were not all the same. At my Dad's shop, we used to stock Bendix and Pennsylvania brands. The Pennsylvania linings were softer and rarely squealed, but did not last as long. The Bendix would often squeal but wore like iron. I can't remember now which one, but I remember my dad saying one seemed to stop the vehicles more quickly. I would think the softer material? You could also get riveted or glued. Not having all that much faith in adhesives, I choose the riveted when
  3. Yep! I've had my share of mice problems too. Them little buggers are hard workers and have done lots of damage when I let my guard down. I don't like killing them, but when they mess with my truck it's time to go hunting. Lols! Living near the Delaware river, other critters have given me considerable grief too. Took the truck out for a spin first time last year and every time I stepped on the gas pedal it would almost die. After several hours of trying to figure it out, I determined a spider had built a nest in my carburetor which completely blocked the accelerator pump from working. I've als
  4. Yep, as stated above 6v starter will work just fine. Mine's been working fine on 12v for over 20years. I once did a stupid thing by hooking 12 volts to a 6v starter on the bench in my youth. without the load of spinning the engine, it rotated so fast that the armature windings bent outwards from centrifugal force and hit the field coils. I ruined a perfectly good starter with my stupidity. Another change you'll have to make is adding a ballast resistor to drop the voltage to your points. I just recently did away with that and switched to an electronic Pertronix ignition. So far is working well
  5. My dad owned a repair shop from the early 50s up until late 90s. He had a Ammco brake lathe and shoe grinder. Anytime we turned a drum we would resurface the shoes to exactly match the radius. That's in the days the drums were worth re-cutting. I used to love the smell of all that asbestos flying around. Lols! The machine was in a back room with no ventilation. Anyhow, when we finished a brake job, the cars stopped like new. If your drums are not standard dia. and you install shoes without grinding, they often will squeal and could make the car pull to one side or the other until they wore do
  6. As far as I know, you don't! You could get a Mopar 12v generator. I think there's still lots of them around, but I would recommend an alternator. They're just a less problematic. The easiest would be one with an internal regulator like the GM one suggested above. Pretty much plug and play once you adapt the brackets. I installed a 70s Mopar alternator in effort to keep things Mopar. It uses an electronic regulator which I mounted on the firewall where the old 6v voltage regulator was mounted.
  7. Lols! Yep, some loving and attention is what our trucks need. Problem is, it's like a woman, how much love and attention? And where do you stop? Too little you lose, too much you lose. If you figure it out let me know. Lols!
  8. I get confused easily, but I'm not following exactly. πŸ˜€ I'm just a shade-tree mechanic. I believe this is the way to check: ? Standard open differential - With both rear wheels off the ground, rotate one of them, the opposite wheel should spin in opposite direction. Positraction / limited slip differential - With both rear wheels off the ground, rotate one of them, the opposite wheel should spin in the same direction. If you have a standard open differential (which is likely), place a block of wood or something under one of the rear tires an
  9. I was thinking same thing as kencombs. Broken axle or stripped spline? Perhaps it was the axle wobbling on the driver side and not a bent drum? Let us know what you find.
  10. I'm relieved! I try to stay Mopar as much as possible, but I must admit, there are a couple of gm and ford parts hiding under my truck. Does it count if they're made in China? Lols! I am however, meticulous about not altering anything I cannot reverse to oem. I'm with you on the Chevys. They do not belong in Mopars or Fords for that matter. Flatheads forever!
  11. Welcome Mertz! Great to hear there's another Plymouth truck person on here. Not too many 39-47 Dodge guys, let alone 39-41 Plymouth fellas / (Being politically correct) and ladies. I think I speak for most of us? We like pictures! Not to meaning to UN-inspire, I've been working on my truck for 41 years now, and it's still not finished. lols. This is a great forum!

  12. Just another thought! You likely have a 4.11? You may be able to find a 3.90 ratio original style pumpkin differential. I think that's the highest ratio they made for these rears? That with some taller tires 650-16 or 700-16 will probably do the trick for higher speed / lower rpms? This way, you don't have to change out the housing and associated changes needed to do that.
  13. Mopar alternator! Frank's posts reminds us we should be committed to Chrysler Corp. Or in my case, perhaps, committed to a mental institution? πŸ˜ƒπŸ˜ƒπŸ˜ƒ
  14. Hey Frank! Does this mean Borg Warner T5s are sacrilegious in our Mopars? πŸ˜‰
