Well the electric fans do free up a few pony's. Flex a lite sells a nice dual 12" setup with shroud. Ron Davis sells a very nice aluminum radiator with dual fans and shroud. Be Cool products another good one. Some sell a radiator/fan shroud combo sized ready to go. See if there is something for the Mustang. I'm sure you will find a few nice setups. However the price will also reflect quality in some cases. Shop wisely! G.

P.S if a "period correct" look is not critical look at the Edelbrock water pumps. Aluminum and can be polished ir painted to suit your taste and complements the radiator cooling factor. Flow you know!
