For anyone keeping score, I used an All-Aluminum Radiator 1942-1952 Ford Truck with Chevy Conversion Part Number : 166-EC4252CH from Jegs for just over $200. Changed the lower rad hose to 1 3/4 for the rad, removed the petcock and added a nipple for the defroster. For about $230 I'm crusing again and it's cooling awesome.
