Brian,
what year of truck do you have? I am in the process of doing the bottoms on my 51 and I have completed the major work on the passenger's door.
I bought the inner and outer bottoms for both doors and the outer skin portion is well formed and actually heavier then the original skin. What was a surprise was that the panels were too long and I had to modify them. I did the inside first, grinding the edge of the skin of the lower portion to separate it. Before I started cutting, I tack welded two small vertical channel pieces to the inside to preserve the exact location of the bottom door lip. This was very helpful in fitting the replacement properly. Also I had small sheet metal clamps that help the seam in place while I tacked it together.
Good luck with your doors. I am really pleased with the results.
Fred
