rusty46,
im sure i have got the right patch panels. the corner panels have the ribs in them also. the rib is straight along the entire length of the corner pieces. it looks like if i welded in the corner pieces with the rib matching at the original height to match the door, i will lose the swoop of the rib as it rises around to the back of the cab. i guess i will call carters and see if that is what was intended with these pieces. i was hoping someone had used them, to see what they had ended up with, thanks,
