GM 7.5 comparable to GM8.5 axle shafts?
Can any one tell me if GM 28 spline axle shafts are all the same through the 7.5/7.6 and 8.5 models?
im trying to chase down the spline pressure angle of the 7.5 axles so as to get custom shafts cut.
the only information i can find is on GM8.5s which are 45* pressure angle.
thanks in advance.
