    Picked up at carlisle, PA swap meet. In great shape. Cleaned it up and relubed it.

    I just dont know the application.

    Looks like an 8.2" 10 bolt but with 17 spline side gears.

    Any help?

    Thanks

    I still say 1963-1976 corvette 3 series posi. Just measure a unit I have on the shelf 17 spline a hair over 1 3/4 inches .... 25/32 ish.

    Thanks Jim.

    Corvette application is what I have come up with as well...searching online.

    Evidently there are a bunch of numbers for each series of posi's from back then.

    30117 comes up series 3
    30175 comes up series 4
    32298 is nother number

    I think these units also differ from the 8.2" chevelle units in that they have different carrier bearings and the spline count is 17.
