This is the only pic I could find. At this point in my build I was deleting the vinyl roof along with the lower trim. If you can zoom into the pic you'll see holes where the trim was. I unfortunately think I unscrewed a nut from the gutted interior to remove that trim whether I had to or not. I looked in the 67
owners manual as well as the 68 supplemental. and found they were vague with this particular molding detail. Like I said I think the above window (drip edge) molding was attached with adhesive.
Sorry I couldn't be of more help. If I can find more pics/ info I'll send it your way.
Good Luck!
