And the Beat Goes On

Grandson decided to change oil in his 2001 Elantra and ended up stripping the threads on the oil pan where drain plug goes in (too much King Kong). I am considerting using an oversize, self threading, drain plug to make things right, any other suggestions. I assume I am looking at a 14MMX1.50 threaded plug (OEM) and I will need to go one size larger (comments).
