Sh!t, looks to be in nice shape to me! You weren't kidding with the p/u doors. Did you fill in the gap or do you plan on putting burb/panel doors back on? Any of the board vendors will sell that patch. They are a little pricey @ around $80 per side but I hear that they fit good and save a ton of work.
Try Ricks Pickup Parts, Mothertruckers, Classic Heartbeat, Athey's or????? I believe Ed @ Mothertruckers is the closest to you... He is in Florida.
