TTop weather strip/moulding: white pieces

[left shin]

The 300zx I have came with the weather strip detached from the drivers side ttop. I have the weather stip, but I can't seem to attach it to the ttop because the white pieces that the screws go into are missing. They are the square shaped pieces in the image below.




I need help finding these piece and any help would be greatly appreciated.

Got no response and could find any information on the net so I just bought a replacement. The rubber has worn of on the older one's so the new one stands out a bit. lol.
