So one small update:
Tearing down the factory parts on the axles. Driveshafts and radius arms are off. Writing down the axle codes for later documentation and something was different than I remembered. I know that there were two sets of these axles already removed from the truck sitting next to each other in the salvage yard. The set that I inspected carefully were not the set that I ended up getting BUT I read the vin code on both trucks and they were the same as far as axle gearing. So I got back in the house and it was bothering me so I ran the codes again. I thought I had 4.10 gears and as it turns out My axles have 4.30 gears with a limited slip. Oh well, even better! Glad I screwed it up well enough to get the two that were the same. Geez....
Forgot that I am missing one of the leaf spring brackets for the drivers side. Got to go back to the salvage yard to get the one I am missing. Crap.
