I know quite a bit about the 8.8
Its an 1987 axle, that's the best I can tell you. I can't really afford to pull the pan to look for any stamped info. I have all the tools available to install it, and the knowlege.

I'd just call you if you had gave me your number in the michigan forum. =) hehe

I emailed you at comcast.
