1957 Truck Radiator and Air Con

I am building a '57 1/2 ton truck from the ground up. If I use the original radiator with electric fan, do you think it will keep my 350 small block w/air cool?

Also, I am adding air to the truck, does vintage air come with its own condensor? Does anyone have experience with adding air?

I am looking for a steering column that will work with the saginaw rag gear power steering, anyone know what years will fit in this truck?

What about 55-57 chevy truck websites?

If the rad's in good condition it will work. Mid-70's GM columns fit just about anything if you want your ignition switch on the column. Any air kit will come with the condensor. Use the engine fan too, the a/c needs a constant supply of air.
