The rear is a GM Corporate (Eaton).... the front appears to be a D44.

Re: differencial help

Getting parts for Eaton HO-52 & HO-72 rearends can be hard. They are actually very common...GM used them from the late 40s to 72 in 3/4 & 1 ton trucks. I THINK the lowest numerical gear for the Eaton is a 4.11:1.
