Let's not scare him off Drew, besides the tail lights, the grille, the dash, rear bumper, and the wipers which are the only 68 only things I can think of off the top of my head but he can always swap any year grille, open up the tail light openings to get newer ones to fit, 69 dash is also interchangeable in it, and any year rear bumper can be swapped on, so besides those dame exposed wipers there isn't that much that is hard to get if he had to.
BTW, congrats Unkeday on a sweet (rare) find!
