i think that thy have the 8.0" 10 bolt. my colorado has it, and according to many web sites ive visited, they are all the same from trailblazer, envoy, H3, colorado/canyon. I actually just tore the differential out of my truck, and i cant seem to find a new one after market.

Pretty sure GM uses a American Axle rear just like the full sizers.
