The tub is in New York
If you haven't registered on NC4x4, I'll invite you to do so soon! There are hundreds of folks peddling various 4x4 parts there, with many SC folks online. This increases the number of LOCAL eyeballs looking for your parts and should help you find a tub alot closer the NY! IMHO, there's nothing gonna come out of NY that doesn't have a larger/worse rust issues than what you have already!
BTW, what exactly are you looking for? A YJ tub (factory galvanic coated!) to replace your CJ tub?
