I can't find one for the life of me. Looked at Osh, Home depot, and ACE and no one seems to carry them...wtf?

they have 1/8 1/4, then skip to 3/4?? :dunno

I need to tap the oil pan for the turbo install, anyone have one? They are welcome to drop by and watch/participate in the turbo install as well if so desired :)

Thanks!
