    Default Front and Rear Differential Pumpkin

    Are the front and rear differential pumpkins (chunks) interchangeable?

    I think they are, but just wanted a second opinion.

    yes, with the caveat that some front diffs don't have a fill plug and thus will not work in a rear application.

    yea, neither front or rear rrc's have fill plugs on the 3rd mbr, they're on the diff covers. i solved that problem by jacking up the right rear side, removed the hub and axle and poured the spec amount in. i still have to do it that way even after put a iia 3rd mbr back on, the fill plug is a bit rounded off.
