Also i seem to have misplaced my oil pan plug. I would assume there must be a universal replacement? I looked online and it got real confusing jumping between metric and imperial threads. Again, does anyone happen to have a part number or anything?

Is the M250 a truck? If so, it should have the 8RT truck pan with the large clean out plate. I think that drain plug is larger than the ones in a car pan.
