Request help locating the right Radiator

Try the guys at PRC (Performance Rod & Custom).
They can custom build to order. Tell them exactly what you have written here and provide them some dimensions and in a few weeks you will have your problems solved. I used to be a BeCool guy untill I got a PRC system in our Shop Bitch Nova. Needless to say, every car leaving here from now on will run a PRC.
