Looking for a new fuel tank

As the title says I’m looking for a new fuel tank. I have a 1982 cb750sc nighthawk, and I am looking for a new tank as the old one has some issues. I tried to strip the one I have now and found some decent rust through the tank the previous owner had just bondoed over. Does anyone have a spare tank tryout be willing to sell, or know if a place I can find one? I have tried looking on fb marketplace a motorcycle scrapyards, and haven’t found anything, but I also don’t know what other years (I believe 83 is the same but haven’t found one of those either) or models can fit. So if anyone has info on what other tanks could fit that would also be great. I’m trying to just go with a drop in or minimal refit work as I don’t have the tools or expertise to do so.

Any help is greatly appreciated.
