After countless hours of googling and searching on other forums and comming up with no REAL answers to what s10 trucks had which rear end... i tookit into my own hands to find out exactly which trucks had the 8.5 rear end. I work at a dealership so finding out was fairly easy.... writing it all down wasnt haha. if you feel like i missed something or need to clarify feel free to ask or point it out. also i can get just about any GM part number you think of if you need one.

2003-2005 s10 blazer 2wd 8.5 rear, (M50,GU6)

So... for example if you are looking for a 8.5 rear end with 3.42 gears and posi, you can find it in a v6 blazer 2wd with a manual 5spd trans...

There are also 8.5 rear ends in 4x4 s10's but i did not list them... i can if the majority wants them. Hope this helps find the rear end you want.
