I know GM had a gear selection for 61-65 Buick full sized cars with the 9-3/8" diff. The best set of gear I can find is the 3:42's. I have a few positractions laying around and they either have 3:42's or 3:07's I am looking for the better gear sets offered.... any out there?
I sold a a set of 4.45's to someone here on V8 several years back.......maybe they have not used them and would be willing to sell them..... Put a post in the Bench and title something like "Who bought WildBill's set of 4.45 gears....wanna sell them? That might turn up something. I got 2 sets of 3.91's but will never sell a set unless i put 3.42's in TOPCAT.....but that might happen Good luck and Peace WildBill
