identification
Hey guys and gals. Was wondering how to identify my front/rear gear housings if there are no #s. They are both 10 bolt but that is all I know.

Re: identification
That would help I guess!! Sorry about that. She is a 61 1000 series 4x4.

Re: identification
Without seeing them, I would expect they are Dana/Spicer Model 44. These would have irregularly shaped 10 bolt covers, not round. If they don't both look the same, please post pics.

Re: identification
Ray,
I always thought that the "10-bolt" differential (cover) referred to the GM or Corporate diff. Could it be that this described '61 1000 4x4 is a Chevrolet?

Re: identification
Those are two completely different rears. The GM corporate 10 bolt has a cover that is more or less round. The Dana 44 cover is sort of hexagonal.
Now I have never looked at a GMC 61 4WD closely enough to see the rear. The Chevrolet 1/2 ton rear for that year has a removable center section (comes out from the front) as well as a round cover. Chevrolet 1/2 ton trucks changed to a rear with a 12 bolt cover (not the same as the car 12 bolt) in 63. What most people think of as a 10 bolt wasn't used on trucks until sometime in the 1980s. If you need more help identifying what you have, please post a pic. Ray Last edited by raycow; May 14th, 2013 at 03:52 AM.
