89 Axles

Heres my next problem i just got everything straight on the lowering kit and the rear on the other blazer was pretty much screwed. Its a 89 s10 4x4 7.5 inch rear 4.3l and i need to know how many spline axles i have im pretty sure that there 28 spline but i need to double check before i order my posi unit. I cant check my sefl becasue the rear is at the mechanics shop and hes on vacation for the next 2 weeks. another question is 200 a good deal for a complete rebuild of the rear this is just the work its self ive already spent 300 on gears and a rebuild kit. Thanks for any help.

It should have 28 splines, I just bought one for my 98. It has 28 splines and the axle is suppose to fit 88 - 98.

BTW Don't buy axles from summitracing.com. They are not the right size. They say that they are direct fit, but the axle is 1/4 inch too long and the diameter is about .020 under which causes the seal to leak.
