[oletrucks] Part ID help needed

[WILHELM GORDON <gvwilhelm@home.com>]

Hello out there!

I need some help identifying the rearend in my 51 GMC 1/2 ton.  I don't
think it is original.  The part number cast on the drivers side front of
the case is 8707840.  The rear cover is held on with 10 bolts and is
basically round.

Any help would be appreciated!
