IMO you should definately keep the gunmetal gray paint job. I'm in the process of restoring my 71' roadrunner that was origionally curious yellow. Gun metal gray is an awesome color with a little metallic in the sunlight. And with the GTX's and Roadrunner's being the pedigree of plymouth cars, not disrespecting anyone elses ride, it is smart to keep the origional color so it'll match the fender tag.
