For sale Fresh Plenums.

These are never used fresh air plenums that I bought a few years ago since I knew sooner or later I would need them. I don’t remember the source. But they are a lot more sturdy than the original ones. I believe that an owner can trim the edges smooth as needed and install as an owner produced part. Check with your A&P about that. All reasonable offers will be considered and I’m just not aware what I paid for them.
