I just got a full set of weatherstriping for a 280z. Here is the list.... Cowl To Hood Seal,Windshield Seal,Quarter Window Frame / Body (LH&RH),Quarter Window Glass / Frame (LH&RH),Sill Edge Seal (LH&RH) Goes Under The Door, Door Seal (LH&RH),Rear Hatch Seal Inner, Rear Hatch Seal Upper Outer, Rear Hatch Glass Seal, Rear Hatch Seal Lower Outer (LH&RH), Window Door Frame Sash (LH&RH).
It looks to me like there is two more that are either extras or ???
Maybe this will help.
