67 Barracuda Notchback Headliner Hardware

Perforated or non, no difference, just preference, and for numbers people what was in the car when built.

Do you have the clips that the bows fit into on the sides, or the springs that go from the rear window frame to the rearmost bow.
Every 67 B'cuda notch I have had did have "snake bite" perforated head liner material.
Those 2 little hard wires that tether the rear bow are must have since the head liner is stretched forward for install. Only other item I can think of is the odd, almost diamond, shaped sail panel boards.
Put the screws for sun visors, dome lamp, etc., in their holes so you can locate after head liner is up. And of course the wiring for dome lamp needs to be in place.
