Hey! So yea its stripped. I tried some of that thread repair crap with no luck, well mimimal luck, but the threads arent good enough to seal properly. The plug in there now is a 10MM x 1.5. It looks stock, but not sure. So the question I have is. I bought an oversize drain plug and 12MM tap. The drill size will be approx 29/64ths. Any ideas how large I can go on this project without compromising the case?
