Rear end choices (modified).

Well, I guess it's too late to ask now, but what body is it going into? The reason I ask is because a 70 and earlier B-body 8 3/4 fits nicely under Dusters, Demons, Dart Sports, and 67-69 Barracudas without having to narrow them and they are big bolt pattern. They are fairly common to find for sale as well and at a lower price than A-body models. All you have to do is relocate the spring perches to use one in an A-body.
