If you're going to modify, why not go to a late-model crossflow radiator while you're at it? I had to do this when the radiator from my 59 carryall was stolen while the truck was stored in a tow-in lot. (It had broken down, and before I could recover it from the towing service, somebody helped himself to the radiator!) I used the lower mount assembly from a rubber-mounted crossflow radiator, and fabricated an upper hold-down assembly from sheet metal. It worked OK, including a cross-country trip from California to Tennessee, towing another vehicle.
