Re: 1983 chevy SWB Rear end

Least amount of problems would be 82-87 Pickups with 10bolts and 88-91 Suburbans. (2WD if yours is a 2WD)
73-81's will work, but you have to have a hybrid U-joint.
but dont quote me on that

Gary,
Thanks for the reply and the info.
I'm installing a 10 bolt rear (3.08) out of an 84 chevy swb. I'm removing a 10 bolt (g80 that has a set of 373's limited slip)

Tony

Re: 1983 chevy SWB Rear end

why ya swapping 3.08s for 3.73s? Bring me that 3.73 rear and ill put it under my 3.08 truck! haha.

Shoudlnt be that hard. When we did my camaro (Same 8.5 10 bolt) we simply popped the cover, pulled jungle pin bolt and c clips then slid axles out, unbolted the brakes, then housing out, new housing in, brakes back on followed by reinstalling axles c clips jingle pin and cover. My brakes were good on my car and the new axles backing plates were a little rough. It should be a relatively easy swap any way you go about it. Dont crimp the brake lines though.

Swapping out for hywy gears and better gas mileage (hopefully)
I'm running 283 sb w/a th-375 (same as a th-400) the 400 is going away as soon as i have my th-350 rebuilt.

Re: 1983 chevy SWB Rear end

th375 a or b? one is a th350 with a 400 output, and ones a th400 with a 350 output, pretty neat to me. I assume the th400/350 output.

With a 3 speed no overdrive you should love it. i leave my truck in 3rd (1:1 most of the time) with my 3.08 gears and 235/75/r15s. With the 700r4 and 3.08s overdives almost useless.
