Are you going to try and install studs someway, or just use little screws? I'm adding vinyl top trim to my 70 Duster, and had planned on using small screws that will fit the clips.....if I can ever find the clips!
I’m using screws. I bought the clips from Classic Industries. Part number A1011K. Comes in a group of 10. I believe there is one clip that is different than the 3 plastic clips but have not figured out what that looks like....yet.
