I have followed your post from the very first. Looked at all your pictures and used some of the things I saw and read to help me on my truck. Wish I had known how to post pic before now. Could have posted them and gotten advice from the folks on here. I have put together an album on Photobucket that I will post a link to soon.
I see you are going to work on your door bottoms and skins. One of the things I would do differently, if I where doing it again, is tack weld in two or three spots on the new pieces and then put the door back on the truck and make sure the new pieces line up with the fenders and step up, then weld them more firmly. I had to grind off the welds on one of mine and start over. Not a good thing. Take care. Jim B.
