I knew finding the part would be close to impossible. I was referred to a local rear-end shop who referred me to Dutchman Axles. You either send them measurements on a form they supply to to you, or send the axle in and they will do the rest. They are charging $225. per axle and I'm having a set made. It really beats the PITA of changing the rear end or waiting/hoping to find a replacement. The axles on my truck were made from 60-62 only. On top of that, they are specific to the optional posi rear end. I don't think I would find one soon. These will also be stronger than the originals - the choice is a no brainer.
