Last night I set about repairing the damaged tub rail on the passenger side. I did the driver's side a while ago but didn't take many photos. This time I tried to document it a little more thoroughly, just for
@RevISK.
Here's the spot where a PO hacked through the tub in order to install the shortened cab. Top-level work, to be sure:

They made such a mess that my first move was to cut the whole thing out. You can see that even this area of the truck is somehow bent out of shape. This poor old 40 has seen some pretty hard years...but thankfully those days are done.

With the damage cut away, I was able to measure the opening and cut a section of square tubing to fit the inner part of the rail. The edge of the tubing matches the corner radius on the original steel, which is a bonus. Here I'm still refining the fit-up:

After grinding and filing, the piece is starting to fit well. My next step was to cut a small piece of 18ga and tack it to the outer edge of the tubing.

I then removed the patch and fully welded the vertical piece to the tubing. It's welded on the back side as well.

After grinding the welds (mostly) flush, I welded it in and ground the welds as flat as I could, given the pre-existing distortion in that area.

The next step was to measure and cut another piece of 18 gauge, shaping it with hammer and vice to match the profile of the outer tub rail:

Here's the piece set in place and ready for welding. The 90* flange at the top is folded over once the patch is mostly welded in: to do that I just use a hammer and dolly to fold it until it pinches the inner piece.

I forgot to snag a pic of the finished product, but I'll do that next time I'm at the shop. It'll need a bit of filler, but at least it's strong now, and looks a hundred times better!
