John you should be able to fix that tank. They have this new product out for sealing gas tanks. The post 60K tank sits higher up off the trunk floor also. It could be just be serendipitous they sit higher, but they do not rust out so quick from being underwater when the trunk drain hoses fail. Anyways I think the pre60K tank will drop right in a tr2, but I have not tried it. Buying new is smart when it comes to gas tanks, but sometimes I see old ones that might be ok on eBay. If you do buy new from the guy in southern Cal, make sure you flush the tank out good because they are full of welding debris. His tanks are made with thicker metal, but I think there is something different with the inner baffles.
