Hey guys ,
I'm planing on replacing the cab corners. The p.o gave me them my question is do I have to use the whole patch panel or can I cut it and just use the bottom half to patch the lower half,I circled what I'm talking about...
Also in the second pic there is a lip that folds over the door sil and my patch panel does not have this lip. Is it necessary to have the lip

Thanks dan



The part i circled os what im talkin bout





The lip i was talking about is in blue

 

You don't have to use any more of the patch piece than you have to. The smaller the better, imho. Just be sure that you use enough to remove all the offending rusted metal so it doesn't come back to bite you later.

The 'lip' is where the factory cab back panel wrapped around and was spot welded into the door jamb. If your patch doesn't wrap around, you'll need to leave the door jamb part alone and cut/patch on the outside skin. You'll want to butt weld it the same as the rest of the corner patch. It looks like someone already tried to cut the spot welds in the jamb. You'll want to reweld those and dress them back flat again.

 

My panel has the lip on but does not fold over like the stock one does

 

Sounds like you will be welding inside the door jamb. That isn't the simplest to grind but not a bad place to put the repair seam.

 

Thanks guys for the help any other tips

 

Use as much as you need. I stayed out of the dished or indented part to make it easier.

 

You might take a look, starting at post #50 on my install of cab corners. I only used what I needed to get to solid metal.

It is always good practice to keep your patch panel as small as possible, replace only the damaged metal where possible. Here is a small patch I did on a 56 F100...I like to leave the cab mount bolt access in place where possible. Any portion of the body that has a seam or bend provides a lot of support to hold the metal in place and prevent warpage.
