I did my own twinplug machining. I matched the angle of the original plug. I used the upper cover to determine the lower cover holes. I drew it up in AutoCAD for precise location and I was precisely about a 1/4" off which puts the spark plug wire at a bad angle. I've got a brand new set waiting for me to machine. I haven't removed the incorrectly machined one's, but I don't need them, the problem is I doubt anyone else needs them either.

adomakin, even for free I doubt it would be worth the shipping to send them to you.

If someone wants them, I can send the AutoCAD drawing so they can see if they'll work. I just hate to send them to somebody else just to have them $hitcan them.
