10 bolt rear identification???

[edwardsss]

I have a 2003 Chev. Tahoe, LT, 4x4, 10 bolt rear, 3.73 gears, G80 Gov lock. I am unable to find any axle housing tags.

How do I determine which 10 bolt rearend is in the truck? There appears to be three options, a 7.5/7.6", an 8", and an 8.5/8.6". Is there a stamp on the housing?

Thanks for your assistance,

Ed
