In taking my 71 Duster appart I found numorous holes that had been added over the years and the engine bay had been repainted. Could you post a few good/clear shots of the front floor pans looking straight down as well as a good shot of the firewall and both inner fenders so I can have a look at all of your factory mounting holes, etc.? Also a few good shots of the core support blackout paint, especially around the edges so I can attempt to duplicate the pattern (you'll need these too later on!)
