Looks like some seriously well done work there!! I should have called you!!
I took an easier road as I just needed a driver side portion of the pan. The rears still look brand new and the pass side was almost as good. Obviously water had gotten in on the driver side at some point and sat there hiding and doing its damage (I redid the wiper pivots so that won't happen if that's where it came from). So I cut out the bad and welded in the new pan. Mr. BFH helped alot priot to welding. Also spent time after welding using a spotlight looking for pinholes where the welds may not have joined up. Had just a few - welded them up. No pro welder here but it gets the job done. Pretty happy too how tight it fits up on the bottom too, very little gap if any at all. Will tidy that up later in the build.
Now waiting for those sticky sound deadener panels to arrive and line the floors and will then reinstall the carpet and seats.
Crappy pic but shows the idea. 1 piece pan welded in.
