    What is a Mopar 8 3/4 diff? What would a posi unit from that differential fit in? D44, D27???
    I could go online and look for an hour, but I know many of you out there know the answer.

    Thanks

    If the 8 3/4" has a sure grip limited slip then you can use the guts from the sure grip in a Dana 44 Powerlock. They use 30 spline side gears and it used to be common to rob the guts from the sure grip to convert a 19 spline powerlock to 30 spline. Nickmil
