From all the reading I have been doing, I am under the impression that all of the TBSS and TB EXT, along with the Envoy XUV have the 8.6 rear end underneath. From that impression, I found an ebay ad for a GMC Envoy XUV rear end (ratio and locker not important, because I plan to regear it and put a Detroit locker in it), so I ordered it, but the one I received is the 8.0 in like the one I already have.

Someone please clarify if I need to get on them for pulling and sending the wrong one, or if I am mistaken and if so, how to ensure the next one I buy (after reselling this one) is the 8.6.
Thanks in advance!!!
