Folks, 37 GC and I have been PM-ing back and forth trying to get his oil lines hooked up, and now I'm stumped.

This fitting we see here in his picture, he needs to hook his oil filter canister line to this opening.....anybody have an idea what size this is? Or what thread it may be?

37 GC, what engine, and what year engine is this on?
