Highly recommend
US Radiator. Stamped top, and options for aluminum or copper/brass, and they also offer different units for engine swaps, etc. I had previously used a nice aluminum radiator from Auto City Classics in a '53 Bel Air (stamped top, so looks OK, lifetime warranty), but it was not a bolt in with the stock 235, and took a little work to relocate 1/2"-3/4" forward to clear the fan. The US Radiator products are bolt in. I sourced mine through Walton Fabrication. Todd is easy to work with, and gets considerably better (lower) than list pricing.
