Yes, I'm an idiot; turned the drain plug on my transfer case the wrong way and stripped all the threads out of the case and buggered the threads on the bolt somewhat as well.

I was hoping to find an easy fix, but this is proving to be somewhat elusive. I haven't calipered the bolt but the front diff fill plug is 20mm x 12mm and looks similar. As one would expect, though, I can't find any metric parts in the local market.

Any idea if a 3/4" self-tapping drain plug would work? I think 3/4" is smaller than 20mm but maybe with the threads etc. it's somewhat oversized.

How about heili-coil? Again, I can't find metric, but I'm wondering if a 3/4" tap and heili-coil might allow me to use my 20mm bolt or I should be able to pick-up a 3/4" drain plug.

Any other ideas? Right now the drain plug is being held in with plumbers tape and blue locktite <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
