I'm replacing the tank on my '63 330 Sedan. My old tank is in decent shape, using the O-ring seal. The new tank is using the grommet style seal, so I'd like to find another neck for my project. I would like to find one in nice shape, No Rust, as I'll need to get it looking like new. I think all the '63's used the same neck, 330,440, Polara's, 2 or 4 door. Let me know what you may have. Thanks
