Locking Diff's ??

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.

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