I can not imagine how you bend a stock 30 spline axle, let alone a 35 spline axle
I have broke several stock 8 3/4 axles racing them, they had twisted 1 to 2 full axle splines on the left axle before breaking
I replace them now when they have one full spline misaligned
I put Strange 35 spline race axles in my old street Duster, never had a problem with them in the 8 3/4, they where dead straight even after I bent the crap out of the 8 3/4 housing and swapped them into a narrowed Dana 60 housing
