This is 2 questions...1 who manufactured the OEM posi for our cars? was it eaton, or someone else. and Next where can i find OEM replacement clutches for one. after removing my stock one from my car i wanna rebuild it and install it into my S-10(good thing they use the same size axle)

 

It was Auburn.

You can't, unless somebody has some NOS ones laying around. Even Auburn doesn't sell them.
