Need "Full" Floors 73 Duster

My Freddie Flintstone mobile (see signature) needs floors. I don't want to purchase new partial pans; front both sides and rear both sides to try to weld onto rusty toe kicks and rear seat risers. I'm looking for a full floor unit or donor car that's not totally incrusted w/rust. A donor car would be preferable as I'm sure there will be other metal panels I'll need once I get started, but I don't want to start until I know I have the floor I need.

Thanks
