Since the car needs a total repaint, probably a new tailpan, the front sub completely detailed, among other items that you will discover as you proceed, there is really no 'survivor' status left. The original drivetrain is great, and the interior is nice, but this car is not a survivor. I'd pull the 1/4's off, replace the outers, and brag about all the original items and hardware that you only have to clean up and reuse
BTW, love the color! No v/t, no moldings, XT's, 4sp, 731, when is my luck showing up = jealousy
