I bought a BE Cool Aluminum radiator on e-bay 5 or 6 years ago. The seller sold all returned be cool radiators from the company. These were considered used but the one I got was never installed in a vehicle. It was specifically designed for 49-53 Chevy trucks. It still carried the full warranty from Be Cool. I called the seller before hand to be certain that I wasn't buying a faulty radiator. The cost was half the retail cost of a be cool rad. I am running the same setup as you, small block chevy, 700r4 rack and pinion steering, no AC. We have never had a overheating problem, radiator was a perfect fit with the original radiator support. I have since given the truck to my son, so all the paperwork is with him, but I will try to find the sellers name so I can pass that info along to you. I am presently restoring a 52 Chevy Styleline coupe which I put an aluminum radiator in, but not a be cool, found a good fit at the Goodguys show in Columbus last summer for a good price. Coach Frank
