Thanks Guys,
I got it out of the shed today so I could look at it a bit closer, and it does only have a two letter date code. As near as I can tell (and I'm no expert) I don't think its ever had more than the cover removed, everything looks as if it's as it came from the factory. All the bolts look to match each other, and it has GM on the ring and pinion.
2blu442, I'm in Michigan...so, yeah kinda not very close to where you are.
I would really like to know what cars might have came with this rear.
I took a bunch of pic's and uploaded them to photobucket, If any one would like to check em out.
