Chevy truck radiator from my 64 C10, the truck was originally 283, this rad has sat behind a low horse power 327 for years with no problems, core size is 17 1/2 inches high, 18 1/2 wide and 1 1/4 thick, overall size 22 1/2 high, 18 1/2 wide, bottom hose is 1 3/4, top hose 1 1/2. It worked fine before removal with no overheating issues or leaks. There are a number of bent fins, I've photographed the two bad areas. Made by Harrison, no idea what to ask for it so I'll say £50 plus £10 postage. (I'm sure someone will tell me if I'm way off :shake Will definitely fit 63-66 trucks not sure about others, any questions please ask.
