Finally Some Pictures of my 1969 Dodge Dart GT
My car had the same rust in the floorboards that yours did, I purchased some really nice quality patch pans for the floor towed the Dart back to my friends body shop in Tempe and he installed them and they turned out perfect. And once again I was so fortunate that I brought my Dart to Az. in 1981 cause the only rust was those front floor boards. At least it appears that yours is being repaired as good as new. It will be really nice when done.
