this is what my drivers cab corner looks like , the only bad spot to fix on the cab but all the patch panels I see only go up 10 inches from the bottom . I need a patch panel that goes up 16 inches ... prefer 18 inches if possible to get it 100 % . Is there anyone out there that makes this ?

right now that is a bit much metalworking for me , I would even consider used sheetmetal that is in better shape .

 

I would purchase 2 left side cab corners , just cut off what you need for the upper portion this should give you the proper curved edge you would need with very little fabrication.

 

now that sounds like a pretty good solution Mike , I thought of bending a piece of sheet metal but that area has a compound curve in it .

Using a piece of a second corner would keep the curvature ...... Great idea
