I have an '88 Camaro SC with a 305 TBI. Ibelive the axle is a 2.77 ratio. Does anyone know how many splines are on the axles?

 

if the rear has a 2:77 ratio it is a 9-bolt and about the axles,,,if the rear is an 88 it has 26 spline axles,,,i am almost positive that most 89 and later rears had 28 spline.
