That part is just the tip of the iceberg as far as the A.I.R. system is concerned. Air pump underneath the diverter valve, more hoses than the a/c system and hard lines to each cylinder of the exhaust manifold.

Then you have to plug the holes in the exhaust manifold... it is all very doable. I think you are emissions exempt in FL? If so, then removing all this shouldn't be a problem. And it certainly cleans up the engine bay.... you can actually see the fuel pump from the top side :poke:

on my 82, the replacement fittings into the exhaust manifold were 1/4" pipe thread plugs, maleable iron. (black/dark grey in color)

The galvanized ones appear cleaner, but using galvanized in a cast iron header didn't seem like a good idea due to heat handling characteristics.

The 1/4" pipe thread plugs should be available at a plumbing supply, don't count on Home Depot to have them

The other direction, which I was told works too, is to cut off the metal tubing into the original fitting leaving enough tubing sticking out and then pinching it off real tight.... I didn't want sharp ends sticking out on each side of block.
