Here are a few pics of the left side patch panels for the 60 to 66 fleetside. You can see that their not going to be an exact fit. The inner panel is alot different then the original inner panel. I plan on cutting and using the rear patch. Like Napco Man said it going to depend on how much has to be replaced and where. I'm going to have to Fab some of my repair areas. Will post some pics.
