350 with a long shaft water pump. 1948 1/2 ton. My question is do I need to use the alum spacer that connects to the shaft of the water pump and the fan. I should have gone with a short shaft setup. Can't change it now because I purchased complete march pulley system.


What do you think? What radiator and source would you use?
