I see that Ricks Camaros now has exact repro Harrison radiators for Camaros. Camaro did not use a Harrison code UP part 3014090 so there isn't an exact match yet for my 4-row but I wonder if a Firebird version is very far off? They are pricy, however, at $1070. http://www.rickscamaros.com/camaro-radia...-1967-1968.html "This is the most technically correct Camaro radiator that has ever been manufactured. You will find all stampings; bends, text and clips are concourse correct."
