1967 Camaro axle splines

[TJs Destinity]

First time on CRG, absolutely great site.  I have a 1967 Camaro RS/SS, 350 cu. in., 12 bolt rear end.  My question is; did all the 350 cu. in., 12 bolt rear end use 30 spline axles or was the 33 spline axle used on some models? Thank you.

Stock axles 12 bolt axles were 30 spline. Only way to get 33 is aftermarket.
