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

Moser told me that send them to them an they would do it for a 110$ shorten an respline i need it for the bolt pattern .... then got to looken at there site buy the time i ship to them an ship back an pay to have the work done ..... im better off buying a set ... they make 2 different strengths. i was looken at the ones 215$ b body brakes big bolt pattern but they make abody's brake drum size whole list ck it out i tryed the go to machine shop respline an cut but it takes the hardness out of axle make it worthless unless you live in a area where you can have them re harden ... then i look to redrill but my axles have to many hole in them ... why dont no that one either .... so im back in save mood till i get the money for the right ones
