I have a '92 Roadmaster wagon, but it's on DD status so I can't just tear the floorpan out at the moment or I'd happily do it myself.
To my knowledge, B-Body pans from '73 to '96 are INCREDIBLY similar, regardless of whether it's a wagon, sedan, or coupe. I know my wagon has a different spare tire well than the sedans did, amongst other things.
I was hoping someone would volunteer if they're in need of new sheetmetal and they have the luxury of tearing out their floorpan and waiting.
I've already talked to them, and they're interested. I asked specifically to bring pans for our cars into real production, and that's absolutely what I'm shooting for. They were referred to me by a friend from the 1st gen Toyota Celica community, as they're the only place you can get sheetmetal for those cars.

Check them out! They made a Gogomobil pan! They'll do anything. I think the fourth best selling automobile platform in history is a good sell.
