Help with plug size
 

I had this posted over in the 930 section, but figure its more suited here; I used this donor manifold for my 3.4 build. It has a couple fine thread tapings which are not needed, and I would like to find threaded plugs to fit. Any sources or ideas would be great. thanks Philiphttp://forums.pelicanparts.com/uploa...1325547168.jpg
