I have a rear that I need to Identify. It has a casting number of 3790614. Anyone have an idea what this is from? Thanks.

Paul,
As a complete assembly, the 62-3 Chevy II center section is a 100% bolt-in swap for 55-64 pass cars and 56-62 Vettes (accepts the same 17 spline axle ends). But the case, guts, ring and pinion, bearings, etc, are unique to the Chevy II and are somewhat weaker. Their best value is for use as a very good boat anchor.
An excellent upgrade to a 62-3 Chevy II is to swap in a 57-64 posi center section, drill and install 5 lug bolts in the axle flanges (Chevy II axles were 4 bolt), acquire the the 64-65 Chevy II V8 engine mounts/hardware and drop in a SB and a Muncie. It's basically a cheap, drop-in V8 upgrade for the 62-63 Chevy IIs.
