    It will work fine. Consider 4.10's as well, unless you already have or are dead-set on using 3.73's. You will need a flash tuner (or possibly a speed-cal device) to recalibrate your speedometer/odometer, regardless of which ratio you choose.

    Are you doing the gear change yourself?

    I used the Ford shop manual when I did a gear change on a '66 Mustang. There may be someone on here who knows some other techniques that work just as well. Good luck, it's a meticulous job but not one that you can't do yourself if you have all of the required special tools.

    Shouldn't be too tough if you have prior experience. It's simply a lot of disassembly and reassembly. Make sure you have the correct pinion depth or you could have problems.

    see i debating between a 3.73 Trac-loc and a Auburn LSD any preferences from anyone? I like the LSD idea but FRPP i know for a fact will work perfect for the car.

    I'd go FRPP or Eaton.
