I have a 51 3100 with a 58-62 235. I pulled the radiator to have it boiled and cleaned up and the reputable Radiator guy, "Bob", told me its shot, I need a new core at the cost of $448. New Rads are cheeper via the Chevy suppliers but I do have access to some other AD pick ups for parts. The question is are all AD Radiator interchangeable? Is there something I need to be aware of size wise if I find a good one out these parted out AD trucks?

Thanks all.
