In the building of my '40 Ford Pickup --- one of the things I want to really address is the A/C.... having had many hot rods over a long period of time -- The A/C in these has NEVER been worth a darn compared to the A/C in a new automobile.
I like to drive my hot rods -- and I'm looking forward to driving this '40 on the Hall of Fame tour etc - which ends in Texas. I live in Idaho and it's warm but not hot in the summer... but we have plans to move to Scottsdale where it is darn hot!
With that in mind -- we're going to install Restomod Air Membrane in the truck. This is supposedly a dual purpose THERMAL barrier and sound deadener....
