If anybody can help me I would really appreciate it. I just bought a 1978 Sears Free Spirit with a very leaky gas tank. It looks like it has been patched before. I'd prefer replacing it as opposed to repairing it. I am not concerned with the cosmetics so much. It doesn't have to be a perfect fit either, just something that will work. If anybody out there has any ideas I would love to hear them. Thanks! Alex.
