Radiator core support
One of 3 rust areas I need to repair is the bottom outsides of the radiator core support. It’s the area that visible from the wheel well. It was packed full or dirt and debris. For now I blew it all out and sprayed some rust killer in there.
I need to replace the rubber cab bushing including the core support ones. I figured I could do a repair at the same time.
I can tell there was basically two piece that are lapped over each other, it also looks like this on pictures of new one.
I am sure this is a common rust areas. The panels aren’t terribly expensive but the shipping is the same cost as the panel.
Do most people just weld in patch panels? I can brake metal and weld.

I replaced all my cab/radiator support bushings w/ poly ones as the old ones were completely blown out.
The sleeves that go through the bushings are two pieces and just fit together via tension. If they're really old, they might be rusted/fused together.
It's good to know that the radiator support sleeves bolt in from above. I saw a nut on the bottom sleeve and thought I would be able to break it loose from below using an impact gun.
I was wrong...I ended up cutting through the sleeve and bolt just above the frame w/ a sawzall and replace w/ all new hardware.
For the cab mounts, use lots of penetrating oil and heat if necessary. I broke the front cab mounts from below using an impact gun while holding on to the top bolt w/ a ratchet inside the little access hole. The rear bolts I think I broke loose from above.
For patch panels, yes, cut and weld them in.
