Mid 60s C-Body 8.75 axles... cant shorten them?!?

...............Dont run a drag radial or slick with resplinrd axles.......pay the money and get good 1s.........and no u need to harden the splines other wise there like butter.......kim...........
So Moser and the others will happily respline, take your money, and send you back butter junk? If this is true, what a friggen scam. Thought I remember asking about hardness and they said it would be ok? Makes you wonder if they would even run true after the hardening process?
