No, vent windows 67-69 2 door, 4 door sedans and 2 door Hardtop all interchange. Handle may be different style but will interchange as well. Gaskets are the same also.
Only partially correct. The glass and weatherstripping? Sure. The frame/glass retainer? NOPE. So for the OP, you can't get the frame from anything other than a 2 door hardtop. The lower glass retainer will exchange with the 4 door and post cars.
I'm surprised about the glass itself, I was wrong about that. Kinda smart to make the top taller by the width of the upper door frame on the non-hardtop cars. But really, the wing vent frame should not at all be surprising. Hardtops have no upper door frame. The 4 door and post cars have upper door frames, the wing vent fits into those and not its own frame like on a hardtop.
