Methinks a good quality 8-3/4 in an A-body is the way to go!
Easy to swap out the diff housing,even at the track!!!
A word of warning when using standard tube 8-3/4's.
Always put a good strong brace on 'em. They bend real easy!!!
Dana's are well heavy, and more suited to B-bods.
They can get expensive, so most folk go for '9' inchers, ooh eer!
