Water jacket bolt size?
 

Hey guys I seemed to have misplaced this bolt and don't have my tap set with me right now to figure it out. Any idea what size the bolt is for this? Center of picture above what some people use for the oil feed line. Thanks in advance!https://cimg5.ibsrv.net/gimg/www.mia...a1f8ab3f80.jpg

Thanks bud! I'll pick one up today

Isn't that the coolant plug hole? I think you are also going to need a copper washer to seal it up.
