Goodby Air Injection System
 

My 1977 911S still had the air injection system on it when I bought it, for some reason that I don't quite get. I'm in the process of solving that problem...

So a simple question - is there a part number for ordering the right sized (and rust proof) plug to seal the hole left once the air tube/union (part 911 113 145 02) is removed. I'd like to plug the hole left by the check valve too, if such a thing exists. (part 911 113 115 01)

Thanks for the insight.
