"You'll be more money in a brass radiator" I appreciate your concern. but I don't really care about the cost that much. If i had the $500+ i would go spend it on a copper one or have a custom one made. I have $1600 into my diesel radiator. Specific to the diesel. GM or nothing.Finding a radiator for a buck and a half ish is gonna be tough. Aluminum or brass. And a brass one will more than likely need rebuilt. You'll be more money in a brass radiator after finding a place to rebuild it as a good quality aluminum radiator. (Which is readily available)
