[mopar420]

I have a 72 duster with a 318 auto in the floor and a 72 4 door dart with the 318 auto did either one of those come with the 8 3/4? Im wondering cause im tryin to get together a good rear for my 74 duster im goin to do a ladder bar kit and all on it! any help would be nice?

It's possible either or both came with an 8.75. I parted out a 71 Valiant 4 door slant 6 904 with a factory 8.75 and KH disc brakes. Quickest way to tell is to take a look - 8.75 has a smooth, no bolts back side, all the other Mopar rear ends came with bolt-on rear covers.
