I just picked up the plug today actually and it fits neatly in the whole but is in fact too small, I got the M16x1.5 bolt, and even without cutting the end down it fit the whole bolt inside loosely... maybe I'm just retarded and didn't push it in all the way, before I make a rash statement I'll go check again actually. *revision possible tomorrow8
As soon as I get this crap figured out I will assemble all of this information into a write-up with Carl and others getting the credit cause I sure as heck had no clue. Then we can eliminate all the bazillion threads asking how to to make PS work.
