I assume that all BBC '68-'72 A-bodies had one that would work ? It seems that I remember reading that some Olds and Buick '71 & '72 A-bodies had one. And I think I read that the 455 T-37's had 12 bolts ? Not sure tho. Lots of guys are trying to get about $1500 or more for an original 12 bolt. Does anybody have all the info on this subject ?

Then, of course, for those on an unlimited budget, most of the rear end specialty companies can fix you up for about $3000 or a little more.

Yep, the Buick is the way to go...you dont want the olds rear, as im pretty sure they are some weird deal... In my case, i can legally run a BOP hoghead from the early 60s, since its legal to run a rear axle from the same manufacturer, and i have a good selection of go fast parts for it. I would just have to get it narrowed, and have all the brackets and perches relocated...but an 8.5 would be ok, with all the good stuff in it...ring and pinion would take a beating, but probably hold up fairly well...but, if i can ever get the funds together, i will have the big Pontiac rear axle retrofitted...
