The US Radiator link also has a link to Cap-A-Radiator which is in Farmingdale N.Y. I have dealt with Bill Carberry and one of his workers and found them to be super guys. I bought my Griffin radiator for my 37 pickup cheaper through Bill than I could get it from Griffin.....who really didn't want to sell it directly to me anyway!
Bill has some good reading on his site as well if you have a few minutes to read.

Just as a tidbit, Bill also list a heater core for the Fresh Air Heater but yes, its costly, $225 but if your going to run out 50 dollars worth of gas looking for one then sit at home and order it and apply the savings to the radiator!

Denny, let us know what you decide to do. It appears you have many options!!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
