Title: Windshield frame patch
Post by: AugustD on December 28, 2016, 04:33:50 pm
I'm looking for a way to patch the bottom of the frame where my windshield sits in. The passenger side corner is in bad shape. I'm looking for ideas or anyone with an old cab willing to cut and sell a piece. Thanks very much

How big is the hole?  Pictures ?  I patched 5 holes in the bottom part of mine but they were all in flats and didn't extend into the curves. I cut them back to good metal in a rectangular shape. Drilled a 1/4 inch hole at each end. Spotted welded a tab at each end through the 1/4 inch hole and then cut a piece to fit the original cut out and welded it in place. A little grinding, some metal infused body filler and a fair amount of sanding you would never know a hole was there.

I would suggest sawzall and amputating the sections you need from a donor. It will be a cleaner job than trying to fix that in my opinion. I cut a section out of a cab for someone on here a while back. Maybe someone on here has a scrapper they can help you out with.

With that much rot you might have firewall to cowl rot int the seams, how about the cab supports, A pillar door hinge areas.

Might consider looking for another cab.

Would you just remove fender and see how bad it is?

No you need to go inside, peek behind the carpet and firewall insulation, wouldn't hurt to remove the glove box either.

I might have a donor cab that I can section for you.  I am also in the Pittsburgh area (sort of).  I will look tonight and take some pictures for you.

unlike the previous 67-72 generation the squarebody windshield frame and upper cowl panel is in one piece - this illustration shows the windshield frame/upper cowl assembly (OEM #15629646 81-91 (w/hood hinge cutouts and cowl screen provisions); #459891 73-80)

That would be great if you had some donor pieces. Any luck with your cab? Your pm box has been full so I couldn't message you

Wow,...looks just as bad as mine did,....(82 C-10)
When I got the door-fender and cowl of ,...I almost cried,....but what the heck......if you love your truck,...get at it.
I found a donor, and started cutting it in pieces...remember that with so much rot,....the a-pillar are most probably rotten a good bit up towards the roof line,...
The pillar are made of 3 pcs sandwiched together and a tough one to work with,..drill the spots and peel back a layer at the time,...
Just don't give up,...

Water and salt etc. Not nipping it in the bud will allow it to spread
