    I purchased this differential cover a while back - had the shop put it on during gear install.
    http://www.americanmuscle.com/frpp-88-diff-cover.html

    Now I'm in the process of changing the gear oil.
    Got everything drained out, but I cannot figure out how to remove the fill plug in this cover.
    It is some large sized hex.
    A T-50 torque bit is too small and a T-55 is too big.

    Does anyone know what is supposed to fit in there, nothing I have around the house seems to fit?
    I already tried to remove the factory fill plug, but ****ing blo-hio has the thing so rusted, it is not coming out :mad:.

    Doesn't look like a torx, looks like an allen head to me. It might just be the damn screen on the school computer though.

    I'm pretty sure you are right, I just threw the torx bit sizes in there for reference, since I had them here and neither one fit.

    I still use the factory fill plug on the driver side front of mine.
