Another option is a F/M/J axle (Aspen, Diplomat, 5th Ave etc.) The spring pads will be in the right spot for a B body, just that the center pin holes are much larger. Thanks

Up to what years say for 5th Ave. or Diplomat?
Probably going to get this at a bone yard where the Cordoba sits. But if I can get one of those cheaper Mopars the price will be lower.

Thanks again
