I have a 7.5 inch rear end out of an 89 Astro CS with about 142K on it. While the rear end may not be of interest, the gears are 3.42 and it has an open series 3 carrier. It's got a clunk and leaks from every seal, but it was working when I pulled it; I installed a 9 inch. I'm in Carbondale, Illinois and will be making a trip towards PA this week. I havn't popped the cover yet to inspect, but will if someone is interested. Quite frankly gear lube is nasty smelling and I'm not coating my hands in the stuff if nobody's interested.

 

TTT. Also forgot to mention the yoke is for a 1350 series U-joint.
