    That is good to know about the pinion angle. Wasn't aware. I have a 66 B body waiting to get cleaned up and go in with the Dr Diff kit.

    I guess in the end it comes down to how much tire you want back there....

    While I was working on the car today, I noticed what may be an issue with trying to use an A body housing. The U bolts are fairly close to the stepped up part of the housing close to the end. With the A body being another inch in, it would be close. I took a picture while I was there. Just one more thing to consider.

    I don't see where anyone covered this but the Good 8 3/4 A body diffs up to 72 were 4" bolt pattern , after 72 you only had the 8 1/4 diff with 4.5" bolt pattern
    I would look for a B body diff

    I do know the green 70 cuda had 5 on 4.5 but it also had different axles as well. Good point Chryco

    The housing I can get, needs axles anyway so no big deal there,
    could you weld the pad on the axles on both the hi and low area( notching the outboard side?

    The problem is that the outside u-bolt won't fit over the step. If that pad only needs to move 1/2" out, you might just squeak it in without the u-bolt interfering, but you need to measure first.
