The Shop Truck

1971 Chevy C20 with a custom flat bed.
With the core support sorted out, we moved on to removing everything from the firewall so I can weld up some of the unnecessary holes as well as moving the wiring so it's more hidden. I can see a few holes that need to be welded up in this picture.

The patching has started, and it sucks.

The fresh air vent keeps contaminating the weld, I'm not sure what's going on there, but it sucks. I hate welding sheet metal, but it needs to be done. I'm just doing a few tacks and moving on to another location to prevent warping as much as possible.
I'm not planning on making it show quality. My original plan was to put bedliner on the firewall to give it some sound/heat insulation, but I'm a little worried about it being flammable. I also plan on bedlining the underside of the inner fenders, which I purchased new ones for since the old ones were full of holes and rusted out under the battery tray (which I'm also replacing).
 
Few tacks here and there, and move on.
Some guys dis on it, but I like to make a tack, spray air over it, make a tack, spray air over it., etc.
Works great. That's how I did my whole front fender lips.

Technically, you could grind them down some, and smear those seams with seam sealer. It'd almost look like the factory did it :dunno:
That's something they would have done back then.
 
I looked at that stuff for the Tonka. Came to the same conclusion. Not for external areas that will see abuse from the elements.
 
Dang it was on my list of stuff to use, back to the drawing board.
You can use it on the inside if you're looking for the heat/sound dampening aspect. You've got your interior out, perfect time.

I spent some more time out there today plugging holes, then I decided I needed to remove the power steering and brake master and did that.

I'm not sure I'll get much else done until next week. We're camping this weekend, looking forward to using the new tent again.
 
I originally was trying to weld using my TIG, now I have to straighten out the passenger side firewall from all the warping... I ordered the parts I needed to run .023 through my MIG, but turns out I didn't get everything I needed. Thankfully, my buddy let me borrow his welder that was already set up for bodywork.

All the holes I want plugged are plugged now, lots of grinding and sanding to do though.
 
Today I cleaned up all the welds, and put holes back where I needed them.

Prior to this I think there were 7 or 8 grommets with wires going through the firewall along with numerous unused holes. Now the wiring will come through at the fuse block, either side at the back of the fenders and the engine harness will pass through the firewall at the back. The normal fuse block wiring will be retained as well.
 
I had Amber's help out there today so we spent some time straightening out the panel I warped. We got it pretty flat and I put a few skim coats of bondo on. We're waiting on some sandpaper that should get delivered early tomorrow morning, then hopefully we'll be ready for the bedliner tomorrow or Monday. It's a big change from what it looked like before.
