Okay already. :jump: The 8.5/8.625" rear has 30 teeth in the OBS trucks. No guarantee how many teeth your's has, though. I counted them 3 times just to be sure.

My dad was the original owner of my '86, and it came stock with 28-spline axles for an 8.5" 10-bolt rear. May want to break that bad boy down to see (if you're not the original owner).
Measure twice, cut once, my dad always said. Wish I'd have listened my whole life... :laugh:
