Are you using the original carrier? If so then you need to find 26 spline axles from an 88-89 or older. I did this same conversion into a 77 last summer. Use the S10 drums and have 1/4"-3/8" taken off the brake surface inner edge to clear your stock backing plates. I changed the carrier to 28 spline due to the axles were alot beefier than the 26. If you are running a posi with any type of HP, then those 26 spline axles will be short for the world.
OOPS, was trying to reply to the original poster :/

Did all 4.3 with manual transmissions have that shock that mounted longitudinally? Its like a 3rd shock, but doesnt manage any vehicle weight, I think its there to stop wheelhop maybe.
I have no idea why GM wouldnt put the 8.5" rear in ALL of their F-bodies? That would have helped greatly.

Yep. All S10 ZR2's got 8.5" 10 bolts measuring 62" hub to hub. Disc brakes came in 1998 IIRC.
2wd could be special ordered with the 8.5" from '94- on, but only '98+ would have discs IIRC. They were also used in S10 Extreme's and would be std 2wd width

You're right Hogg!
My 2005 ZR2 Blazer has discs and the 8.5 rear. It measures 62 inches. I measured it when I looked for a rear for my T modified. But my stock tire size is 265 75 R15. Maybe just a Blazer thing.

Didnt all the RPO ZR2 "Highrider" S10's get the 8.5" rear axle?
Looks like 98-2004 ZR2's had the 8.5 as an option at least.
Only 4wd got the rear discs 11.6" x .787" rotors , 2wd got drums 9.5" x 2" .
ZR2's had the 31"x10.50" tires and 3.73:1 gears.
I just found these, its teh SS and Highrider packages.
