    What diff do I have?

    2001 T/A ws6 6speed.

    And also what years had what for our cars?

    Which one is considered the strongest?

    I suspect my diff is going to blow very soon unless I baby it, there is sooo much play in it. And nooo I cant afford a 12 bolt or 9". I just need to fix this POS 10bolt until I can get a job...

    Thanks, dave

    DAMN thats a big list lol. I thought just about all 6-speeds got 3.42's, I know I have those. I meant the differential, like do I have an auburn or torsion or what? And what came with what? SEEMS like the older f-bods had auburn's and newer had torsion but I really cant seem to find out.

    Get a salvage rear.... DONT blow your money on "fixing up" a 10bolt.... If you dont have the money to do it right.... when are you going to have the money to do it again????
