Great work. Reminds me of my old 1963 Beetle. Had a similar level of grot. I didn't do the work, but the guy that did was very talented. At one point he had the bottm 8-10" cut out of the car and it was all a bit floppy. By the time he welded it all up, the doors shut first time, the hinges didn't even need re-aligning.
Not for the faint-hearted though, looking forward to seeing the end result.
