T45, if that's work and it looks like it going to get stripped maybe try to make grove with a chisel on the side of the bolt and use a flat screw driver and a hammer.
it seems to me that's what has been done to my plug in the past.

Does anyone know the actual threads on the plug, they want $26 for the plug at Caddy.

interested to know the tread size as well, so I can replace it with a normal hex bolt
