Look up the production codes like I told you in your other post. No one can tell you if you have a posi-trac or not. It's on the production code label in your truck.
Write down the whole list of 3 digit alphanumeric codes and do a search on Google.

It's safe to say that his GM does not have factory front differential locker as they have never offered a front diff locker.

Are you sure about that? Ford did and they usually follow suit.

Not in a S-15 Jimmy.... =)

don't belive GM has ever offered a locking front diff in a s-15
