How Many Splines on Axles
1984 Trans AM 305 engine, 700-4R, 3.23 gears
The rear differential is a 10 bolt with 7.5 ring gear. What Are the number of splines on the axles? 27 or 28?

Re: How Many Splines on Axles
From the 10-bolt FAQ:
How Many Splines Do My Axles Have?
82 to 89 cars have 26-spline axles, though a few 28's may have found their way into late 89 cars; 90 up have 28 splines.
