In order for the Air conditioner (AC) compressor to be installed a portion of the Left side of the engine bay, needed to be cut out.

Exhaust / Heating / Cooling Overhaul Part XVIII (man, I'm losing track Rolling Eyes )- A/C cutout fix and new Engine Foam Seal

It's been a while since posting as I'd seemed unable to finish any one task. Just kept running into problems here and there and kept hopping from project to project trying to keep the work from stalling. So finally it all pretty much came together and I'm back to give ya a look.

A/C Compressor Cutout Fix
When I last left off, I showed you a funny-looking thing made out of cardboard. That was a mock-up of a metal part that would cover this ugly hole that was once poorly covered by a PO's handiwork:

The focus was function, not cosmetics. This would be a temporary fix, nothing more. I sealed the joints and rivets with body seam sealer. Ugly, but functional.

Here it is in place, all sealed up. It follows the contours of the engine tin and does a good job keeping the engine heat down below where it belongs. Down the road, with the engine out, it can be replaced by a properly welded piece from a donor bus.

New Engine Foam Seal
Now that the A/C cutout was covered, I could finally replace the old deteriorating engine tin seal. Here's the new one:

Installation went pretty well (yes, smooth side down and split aligned center front), and it was even a little longer than needed so I could trim to the exact length. Here's a closeup showing the profile:

At long last, the A/C cutout hole was covered AND sealed by the new Engine Foam Seal! Smile

So glad I seen this. I have the same cut out on my 74 bus which had the dealership air installed in it, and I have been trying to figure out why that metal was missing. Now I know why, my bus when I bought it had all the lines for ac but no compressor or anything so it wasn't obvious. I have been trying to find a donor bus to get the metal off of but may go the route you went and make my own.

My '74 has the same cut out and it came with a plastic delete piece specifically created as a cut out delete piece. I'll dig it up and take a pic. This would be a perfect candidate for something to 3-d print.

I have the dealer installed AC as well, compressor still there.

There is a great thread, very detailed, of a guy who installed his AC unit in the same area, but made brackets for it to sit a few inches lower to conserve/replace the cooling metal. Quite tempted to see if the plans fot those parts are available from him.

If I find that thread I will post the link.

Found!

Jake Raby made a system at one time, I think he worked with Gilmore in Florida who installs bay A/C's to mount it under the engine without cutting the body
