Anyone have a 97 RearEnd

I know this just screems "Flame Me", However I am seeing the writing on the wall and every day I come to work the Rear Pinion is making more and more noise. I think the safeest thing for me to do is to replace the Rearend while I can still use the truck to pick up the parts.

Does Anyone on this board know of a Blazer Rearend in the Toronto Area.

I belive that its a 3.73 Ratio However the dealer told me that I have to take the cover off to find out for sure. Anyway Right now I am just looking for Possiable matches. Its 4X4, 4Dr, Non-ZR2, and Not full time AWD.

Any help would be appriciated. Best price I can get on a used one around here is $700.

I love the truck but are the used parts really worth this much?
