There are no aftermarket 8.2 Pontiac 2.93-3.08-3.23 gear set... never have been. It wasn't till a few years ago, that one could get the highest aftermarket Pontiac 8.2 gears avail...the 3.36's.
What Randy's is offering is an expensive kit which includes a machined sleeve to drive in, then to adapt to the smaller front pinion bearing used with the Chevy 8.2 pinion. I first experimented with installing 8.2 Chevy gears (3.36's) into a Pontiac 8.2 10 bolt in the early 90's with an old friend who was changing from a close ratio Muncie and 3.90's to a wide ratio and wanted 3.36 gears.
In order to use the 8.2 Chevy ring and pinion set, one also uses the 8.2 Chevys smaller front pinion bearing and uses the 25 spline Chevy 8.2 pinion flange. Last with an original Pontiac 3R driveshaft, have to run an adaptor Ujoint to adapt down to the small Chevy Ujoint. It's a Mickey Mouse setup...but Randy's makes a considerable sale. Their Chebby 8.2 pinion flange, alone, runs $140, have no idea what they get out of the total kit.
