Rear End

Whats The Easiest Way To Tell What Spline My Rear Axels Are---its An 89 Rs

from what i read 89 and under has 26 spline

thats what i found...

I thought I heard 89 is the year they switched, So it could be either but I could be mistaken.

they switched in 90, 26 spline up til 89...

I see, for once I have been wrong. So this is what thats like. Gotta try everything once.
