Differential cover

An "A" body 8 1/4 should swap right in. Drive shaft probably will have to be changed. I have a 66 B-Cuda that someone put in an 8 1/4, with 5 on 4.5 in bolt pattern brakes. I was all set to change it out, till I really investigated its identity. Ive allways had 8 3/4 rears in my A bodies, till this one.
