In my other thread "The Sled" Ride of 2016, a member -MOSESBURB- pointed out that the Vintage Air Gen 4 SureFit, I bought, might not be adequate for cooling the entire interior and recommended putting in a rear AC. Which got me to start looking into this - He may be correct.
I found an outfit called "Nostalgic AC Parts" that sells what looks like the same kind-of unit that was the rear AC from the factory.
Anyone here have experience with them or this unit? They list it as the following:
"UD-550 OVERHEAD ROOF MOUNT EVAPORATOR UNIT"

Here is the unit / front and back pictures:
