How about all 3? Side windows had no seal for some time I image. You can see where the ash tray on the rear arm rest was been full of water. The previous owner replaced the seal for the rear window. The rust limited to the rear floor panels and under the right rear seat. No where else.
The '73 sat for a long time most of it here in AZ, although the DSO was Omaha, Ne, ordered from a dealership in South Dakota.
I'll post of a few picks. I've already cut out the rust in the right rear foot-well and shaped Dynacorn replacement panel. I'll post of a pic later on.
Merry Christmas and Happy Holidays!!!!

you probably have a leak at either the rear window or the side quarter windows, make sure you locate and repair it too.
Which earlier model pan would work best, in your opinion?
You either need to make it out of sheet metal
Or use the earlier model pans and then make them fit
