I bought a kit for my 41 NASH 4 door car from vintage air. They are very helpful and knowledgable. I recommend you use the biggest condenser you can fit and an electric fan. You need 12 volts. I used the car in traffic last weekend when it was 85+ and you could hang beef in there!! The 46 cab is about 20-25% of the area as well, I am sure you wiil be happy. You do get some warm drafts without the pressurized cabin like modern cars.But still a good move! Hope this helps cauz its 10 min. of typing!! :hammering:
