So guys im buying a late 70's ford truck, im going to take the engine and transmission, also the rear end and im sticking them in my 1957 f100. If the donor truck has a/c can I use all those parts to put a/c in my truck, what extra would I need to do besides of course putting in a underdash vent unit or putting holes in my dash

 

About the only other thing I can think of is an electric fan on the radiator, the ac units need a lot of cooling.

Also a 70's unit wold be R12, not that easy to find.

 

You might be able to use 'some' of the pieces, but there would be a lot of things you would have to custom make. I would contact the folks at Vintage Auto Air. The specialize in A/C kits for cars and trucks that never had A/C to start with. Good Luck

 

Trying to adapt another system to fit your fridge would not be an easy task, I think.

Your donor vehicles' AC would have been incorporated into the heating system, I believe. The Fridge, would not have been. It was an under dash system, separate from the trucks' heating system.

Much easier, though still not inexpensive, to use an aftermarket system.

I do have an NOS, under dash, system I hope to one day install. Sorry to say, it is not a Ford unit. I will still need to buy all the under hood components. Since it is so old, I will have it gone through, all seals renewed , etc. It will remain an R12 unit, as the cooling is so much better. More expense, because the R12 refrigerant, while still available, is sometimes tough to source and is costly.

 

Classic Auto is what I used for my 60, fit and worked great.

 

I was mostly just figuring out if the under the hood components could save me money like the compressor
