Question
Hello. Might you know if the rear differential in a 1996 4wd, auto s10 blazer is unterchangable with a 1994 s10 blazer?? Thanks

Answer
AUTIMN,
  I will begin this answer with these words of advise. A 4x4 Chevy little truck is known as a T10, NOT an S10. A T series is 4x4, an S series is a 2x4. I have owned these vehicles since 1985. With that being said, I'm not sure if the track will be the same. If you call a GOOD salvage yard, they have a book called a Hollander Manual and it will tell them the interchangeability of parts between vehicles. I don't know if Hollander has a web site or not. I might look into that but that is who you should contact.
  I just looked at Wagner Brake catalog and they take different wheel cylinders. One is 7/8" and the other is 3/4". I looked at U Joints and it depends on if it is 2 or 4 door and with or without High Rider package.
  I think the track would be the same but it appears there are other differences. You may need to change the proportioning valve. I'm not sure. The Hollander Manual would be the best.
  I'm sorry this isn't the best answer you need but we have had a death in the family and I'm between funeral home visits. I'll be back on line in a week.
  I hope this helps a bit and good luck..
