quarter window weatherstrip question (09/70 build date 240z)

[KAL7467]

ok i am in the process of a total refresh and am currently working on the rear quarter windows. I have replaced the inner and outer weatherstrip but on the early model their is no third piece that screws on the front where the door weather strip goes. The piece is instead a small rectangle piece of rubber with a notch on one end. I need a picture showing correct placement of this piece. I assume it goes over the screws that hold the window together but know where assuming gets me. If needed I can post up pics of the exact piece and my suspected install location later on when I get home from work. Thanks in advance

they look different from the ones I see on other threads. Maybe a design change...

Here is a link from the MSA website where I ordered them.
