I welded a whole new floor into my Falcon with my brother. Cutting, fitting, etc etc. PITA.VW people are nuts (I include myself in this). We have high tolerances for pain. Now my son is one. I have an old GTI that I was going to reluctantly send to the dump because the floor is rusting out, but now my son has gotten a hold of it and him and friend are going to cut the old floor out and weld in new floor panels, rockers, etc. He thinks its going to be a 1-2-3 cut and weld job (boy is he in for a shock). Its better than playing video games and vaping like all the other kids I guess.
Finished it, went out to a car show in Carlisle, saw they sell whole new floor pans. Either $99 a side or $99 for both sides.
