well i got a 97 s10 blazer 4x4 looking for a posi not really finding any is there anything out there?

 

You first have to determine if you have the 7-5/8" rear or the 8.5" rear. If you have a 2dr w/ manual transmission, you may have the larger diff. From there, just put that application in to a website of your choice and you should turn up some results.

 

hey you could go to the junk yard and find a blazer zr2 and get the diff out of it and but it in yours, because the zr2s have a g80 which is a locker for speeds under 20 mph. Also in lmc truck there is a locker for 200 bucks, it activates by a lever.

 

Is it for off road only or u road drivin this thing? If its only off road u might think about welding it I know people dont agree but done correctly theyll last a while and its cheap just dont get her on pavement

 

With the g80 you would have the avabilty to go on the roads too. Same with the lmc locker.

 

The OPs truck would have to have the 8.5" rear end for a G80 out of a ZR2 to work. You could grab one from another s-series truck with a 7-5/8" rear.
