Can you purchase a new gas tank?, I have a 49 coronet. Got the tank out, but inside is total rust. It doesn"t appear to have holes. The radiator shop says 250 to cut open, sandblast, and seal. The tank has a drain plug which is nice. I'am sure a new (if they make them) tank probably wouldn't have the drain plug. Has anyone ever bought a new replacement tank for your older vehicle? and were you happy with it.
