We used Vintage Air in the 50 I'm helping build. We got a revised glove box so that it would still function.
Moves lots of cold air, and non of the works shows.
I thought it looked pretty good.
It has one long piece that start just right of the steering column and goes all the way to the right hand door. Has three vents in it along with the controls. Then it has one smaller piece that goes next to the driver door for the vent.
They sent hoses, connections, dryer. We told them what engine we were using and what side we wanted the compressor to mount. Also whether we were using a short or long water pump. They sent the brackets we needed also.
We did have to get two relays to make the cooling fans come on either from the coolant temp or when the a/c was turned on.
