I tried looking for new gears but got a headache for my trouble. The used 3:08 gears are out there but are getting expensive. Plus you need the right carrier. I read your other thread about changing over and now I guess you figure used gears are better than none. I agree. I have installed used gears plenty of times and if you know what you are doing it is not a big deal. But the carrier is a problem. A whole rear axle would be easier to find. If I was looking for one I would want a posi carrier. The 8.2 posi uses the old style cone clutches and they are usually shot or about to die. An open rear is OK but with a 400 I would want a posi. The only real benefit to the 8.2 BOP rear is the way the axle bearings are retained with the four bolts at the axle ends. The Chevy style C-clips are garbage. That said, there is another path. I have a 1979 Trans Am 3:08 disc brake rear in my 1968 Firebird convertible. They are pretty pricey too, and hard to find, but regular 8.5" Firebird/Camaro 3:08 posi rear ends are plentiful. I got it to fit by cutting off the spring perches and re-welding them to fit the '68 body. The angle is only a few degrees different but it is enough to stress the leaf springs. I mounted the springs, fit the rear, spot welded the perches, and then took it apart and welded it properly. Can you weld? Have a welder friend? That is a plan. The only thing I don't like is the C-clip axle retainers. They make C-clip eliminator kits and that is nothing more than the old Pontiac type axle retainers like you have now. Worst case you have a GOOD welding shop do the welding. I know a guy in central New York, Seneca Falls. He is John Giovaninni, and he runs Gevo's Gears and Rears.Gevo's I have bought many used gear sets and carriers from him. Always very clean and useable. No junk. He has a Fleabay page too, lots of stuff. Gevo Ebay Look what he has right now: BOP 3:08 carrier And while I don't see any BOP gears sets, he may have them if you ask. Or get a Chevy gears set and just change the companion flange and U-joint to Chevy 25 spline style.Chevy 3:08 Lots of ways to get what you want. Last time I was at Gevo's he had a mountain of rear ends. I'm sure he can hook you up, maybe with a whole rear all ready to go.
