Having trouble finding something that looks clean to plug the holes. Right now have the fittings from the old manifolds cut off, welded shut, and screwed into the MACs. Someone told me to get M22 drain plugs from NAPA and that they worked great. Been to 3 NAPAs and no one seems to carry them. Any suggestions.

Thanks

 

i went to a hard ware store and bought them might be easier to find

 

You'll need to order them. They do have them in the books. If not, a hardware store would be your next best bet.
