1964 dart wagon tail lights

This is a bit of an old thread but I thought I’d see if could revive it since I really need wagon tail light advice. I’ve been failing to find a tail light lens for my friends’64 Canadian Valiant wagon (same as American Dart back half) I’m now wondering if I should start looking for a complete non wagon housing and lens set to try to make them work? Getting a little desperate here.
Have you searched EBay? Started a wanted ad here on FABO? Do you have the part number and do a nationwide search of NOS parts vendors? If you start altering parts, it’s hard to go back if that fails.
