Hey, Raccoonman, I hope you are still reading the various posts in this fiorum. It would be great to have you chime in on some questions others have.
regarding your floor pan work, that looks GREAT!! That kind of effort is way beyond my skills and experience!! I have never worked with sheet metal or a welder.
Your first question intrigued me, about locating a source for new floor pans, because there is a lot of rusted through portions in the drivers and passengers floor pans on the '77 Spider I am restoring. But I plan to learn a little bit about welding, then will attempt to weld in some plates to cover and strengthen the rusted through spots.
