Thanks guys, ok I think I'll use a strip behind the joint. Spray it with weld through primer too. I'll also try this every so many inches and then make smooth and go again.

Maybe the cutting and making it smooth between each tack will help keep me from over heating. I've noticed if I use cut off wheel vs grinding wheel it's not as hot.

I'll post back after I start to repair the inner.

Got my cab corners in. These are very big patches. Do any of you guys ever have to use the whole patch? I'm going to get some then take, something I can wrap and make curve with so I can cut a better line on my cab. Just a tiny bit above current cut. And I think I'll use a piece of the leftovers from the new corner as my backing piece.

I would suggest before you just start going ham on the sheet metal, watch a few videos of guys doing it. On youtube I have followed gibson63, he has a lot of videos of doing all the repairs and restoration of old chevys. Yes they are not our model of truck but the repairs are basically the same.

also there is MobileHotRodRepair - they are his older videos, kind of low budget. But you can get what he is saying by his work. He also does tech videos for Brothers Trucks and has been doing it for a long time. He also on instagram and posts up videos regularly on there.

I didn't use the entire patch. I used only a small part, just enough to cover the rusted out area.

I cut out the rust first. Checked the metal that was left to hope it was solid enough. Then I did a rough cut on the panel to bring it down "closer" to the right size. I was told to use tin snips to do the final trimming and it worked very well. I kept trimming on both the cab and the patch, and test fitting them together until I finally got the patch to mate to the cab the way I wanted. I had more time in cutting and trimming to make the patch match the cab than I did in welding.

On one side I actually cut the patch down some, used vice grips to hold it to the cab and used a cut off wheel to cut both the cab and the patch together at the same time. This seemed to work, but I like the fit of cutting and trimming to make it just so.

I started with the smaller area than I needed so that IF I messed up I could cut it all out, get another patch and start over.

I like Gibson63 videos and have watched a bunch. There are others, but you have to figure out what works for you.

I have to say, I got a pair of these years ago and they come in pretty handy.

They have wider ones too, but I have used these for years.
