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 :/
