baron_ Posted December 21, 2006 Report Share Posted December 21, 2006 I've got a 10 bolt posi from a '67 A-body, 3:55 gear, 3 series 8.2 for a pontiac or camaro i've got a 12 bolt posi from a '70 A-body (chevelle, i believe), 4:11 gear - 3 series carrier with the thin gear i'll check up on numbers in the future $1,000 for either, will come down on the 10 bolt both are complete, both can bolt in and go (one's still under a racecar) Link to comment Share on other sites More sharing options...

baron_ Posted December 22, 2006 Author Report Share Posted December 22, 2006 indeed the 12 bolt is a bad mofo: moser 30 spline forged axles (supposedly 30 or 40% stronger than stock) moser c-clip eliminators was in a '67 GTO that ran 10's and would jerk the tires it's also got boxed control arms, sway bar, drag bags, aerospace disc brakes - etc, but i'm moving that over to my 3:42 12 bolt for my '66 GTO then i'll start hitting a few spots and meeting some of ya'll i blew up my last 10 bolt...was trying to baby it long enough to get all this in order i'd much rather build the above 12 bolt, but the other 12 bolt is a more suitable gear and i don't want to spend $400 just to change the gear in the 4:11 rear when the other one will be quite fine for me the 12 bolt is originally from a '70 supersport, i believe the codes come back as being from a 3:31 posi car (which i assume is a chevelle) CCF code the 10 bolt is an original 3:55 unit from a '67 GTO the 12 bolt is an inch longer than the 10 bolt Link to comment Share on other sites More sharing options...
