Basically, there are a ton of spot welds holding this thing in the car. A weld every 1.5 inches or so. "How do you cut spot welds?" you might ask? Well, with a spot weld cutter of course.
I posted a message on Vintage Mustang Forums (VMF) to request an opinion as whether or not to purchase a Canadian make of replacement panel. The thread initially indicated 'yes' but later changed to 'no'. Too late, I'd already purchased the panel which soon arrived was really not the right size or shape. NPD graciously offered to replace the panel with an import panel free of charge so I awaited the new panel.
