3rd gen 28 slpine axles
 

Rumor has it from 90-92, they used 28 spline axles in the rear instead of 26, can anyone confirm this for me? thanks.

89 and up was 28 spline. 88 down was 26 spline

edit: for the 10 bolts that is. Just be careful if your dealing with 89's cause "supposedly" there are some 26 splines mixed in. I think.
