a body 8 3/4 rear complete

What year model A body is it, I have a 66 Valiant and I think after 72 they are wider.
Is it sbp or lbp ? Thank you

Hey memike, '72 is the last year for the A-body 8 3/4 rear. It will bolt in to your Valiant minus drive shaft length if the 7 1/4 is still in it. This would be small bolt pattern.
