rear end?

[monzaz]

I noticed there are 2 different rears in the pictures. 1 and 2 are the 8.5 10 bolt corp rear pics with bolt in axles and the others axle 4 5 6 are 10 bolt Buick 8.2 rear that has a posi tag on the rear cover. The 8.2 rear pics 4 5 6 you can not find gears for so be careful if you are racing it. Once they blow you either have to find used gears...RIGHT or junk it. The 8.5 is the rear you can get all the parts for. Just so people do not get confused.

The 8.2 10 bolt we call it the GS rear 1968-1970 came with a larger driver side carrier bearing(A36 12 bolt carrier bearing) and the pinion shaft inner bearing is 1.875 and tapers down to 27 spline yoke where is where the weak link comes in. It has the same size spline as the 7.5 10 bolt . The 8.5 has 1.625 inner bearing shaft (like a Chevy 12 bolt) and only tapers down to a 30 spline yoke (which is also the same as 12 bolt chevy).

Have fun with the conversions looks good. I do 12 bolt chevy with 7.5 axle tube conversion rears ...they seem to work great. they are exact width and the only thing you need are the upper conversion control arms. Take care all . Jim

You are correct. I completely forgot the first axle I ran was the 8.2 out of my 70 GS455. It's the pics with the unpainted gear cover. It was a factory 3.42 so I thought what the heck. A 455 S1 makes 510 lb.ft. of torque so it should handle a mild TR,right? Darn near blew the teeth off the cone clutches and cracked the case. Oh well I'm going to Buick hell for screwing up rare parts like that. Yep. No parts availabilty. Scrapped it and started over.
