!AIR manifold plugs?
I need to know what size the stock threaded holes are in the stock exhaust manifolds on a 93 Z28 where the AIR tubes went. I did the AIR removal and went to a few hardware places to try and find bolts or plugs to close those holes off but they didn't have anything that big. It appears to be 3/4" X unknown thread. Nobody I went to could figure it out or had anything. Compression and pipe thread also didn't work. If someone can give me the size / pitch and a store I can go to get it that would be awesome. Thanks.
