Valve Cover for 1981-1987 Hydraulic Slant 6

Nope it didn't have air, I searched a long time to find a/c brackets that are going onto the "new" rebuilt engine
and as far as boneyards selling a valve cover .. if they have a complete engine that they think they may have a chance to sell as a complete running engine, they're not as willing to sell any parts from it.
That and as these get even older than they are, many have been crushed, besides alot can't be "bothered" on parts for an engine that has been out of production for over 30 years,
When I go to the local yards I see less and less piles of core engines laying around of any brand these days
