I noticed the gold 68 fastback that itate posted with the black vinyl top.
Was this ever a Factory option??
Reason I ask is my 69 383 "S" had this trim on it when I bought the car in 1984 but the vinyl top was not on it. The trim molds to the body very tightly through all the curves below the rear glass. You can see the trim in these old pictures from 1987. I recently removed all of that trim in my tear down process and have always wondered if it was a factory option or maybe a dealer installed option. Trying to decide if I should weld up the holes or go back with the vinyl. The fender tag does not show a vinyl top code. This is the only example I have ever seen!
