65 & 66 B-body's are different than 67 up, 71 changed to a corporate 10 bolt. 65 & 66 aren't quite as big a ring gear than the 67 up. Gears aren't avalible. I have a 3:08 posi center carrier & pinion with the shims in order. It isn't hard to set-up. I would sell it for $300. Or I have a bolt-in complete 3:08 posi housing with brakes & emergency cables from a 67 Buick Wildcat, $500. $25 gas discount if picked up. [img]smile.gif[/img] The 3:08 is a nice all around gear, I haven't ever found the 3:23 yet. It woke up my 67 Olds 98, it had a 2:56. My 98 weighs 4680# was raced at the Miller Meet 2 years ago, 14:18 @ 99 miles per hour, 1:99/ 60'. 330 307 3376 or
