Late model rear end

O.K. let's see what we can come up with. First: Mopar A bodies have the engine / tranny combos offset to the right to aid in exhause clearance on the steering box (left) side. You may be able to get away with this by bringing the rear slightly back to the left when you weld on your new spring perches - say split the difference? That should clean up the horizontal plane. Just guessing and desktop engineering here. :)

Second: If that total width is drum to drum, then you have exactly: 59.75" (Ford) - 57.25" (Abody) for a total of 2.5" difference, or 1.25" wider per side for the Ford. That should be easy to compensate with proper wheel backspacing.

Third: Tube diameter is 3.25". I'll have to check, but I believe the Mopar 8.75 rear end has 3.0" O.D. tubes. That might cause a minor problem with the spring bottom plate / shock mount but would (should) be very simple to work around. :)

Hell, for $175.00, go for it.
