Firewall issues 1980 C-10 350/th350/4bbl
« on: May 23, 2019, 02:36:44 PM »
Ready to lay down some paint on the firewall prior to putting the rest together, have a question:

Is it just my truck or do other Square Bodies have jacked up firewalls?

I cant believe how uneven and even dented this thing is, with the tack welds that make a Yugo look good!

I guess I can do some skim coat cosmetic surgery, but wow!

That's after you have to remove the toxic black and grey composite compound ostensibly used to seal the seams...

Class B and C surfaces, you can't expect anything but paint on there.  The only time I have ever tried to paint one it was a medium gloss texture black.

Textured paint is a good call Zeig, anything shiny will reveal the poor build.

Looks like cosmetic surgery is in my future.

When I was still in High School in the very early 1980's  I did a car up top notch, should have qualified as a trailer queen.  I was afraid to drive it and didn't want to take it anywhere I had to park it near anything.  I vowed to never build anything that I wouldn't drive anywhere or park anywhere.  Sure I still won't drive it in the winter junk but not afraid to use it as a truck either.

Great story Zeig, I'm an Olds fan too! Here's the second one I've owned. '66

Do you like the license plate?  ;D

I rebuilt my firewall from scratch but it was a lot of work. If you want to take an easier route, they make filler panels. https://www.sloshtubz.net/store/Firewall-Filler-Panels-Slosh-Tubz-1973-87-p64908794

Hey Johnny, I have a set of those filler panels. PM me if interested.
