Then you know it needs to be kept true to the center section bore not sq to the housing, so it might be your 1st rodeo. Not keeping it true to the center gives you misaligned ends and drag, and sq'ing it and then if it's off when it moves from welding and then working the housing to get it to line up gives you bearings not running right and again more drag.
Axles can be bought at Strange, Moser or you could buy some axles from someone who has a A body and went to better axles.
