    Only if you have a 8.5 with 30 spline axles. I believe a 72 chevelle may still have the 8.2 10 bolt and would have 28 spline axles.

    Im not sure about the starting point for 30 spline rear axles in the rear differential. i know that they didnt start using 30 spline in the front till late 89 and on
