I heard back from the radiator shop, they said my old one is no good (don't know all the details yet but I'll find out). What do I need to look for in a direct replacement? I'll have a look at ebay. I assume the shop will give me some options for a new one as well but I don't want to have to update other stuff as well to accommodate a new thicker radiator (like an electric fan because the new radiator would touch the old engine-mounted fan).
