Sliding window locks 1987 Sea Ray 300 DB

[Pack66Dad]

I am missing a couple of these little black plastic jewels.

The lock is riveted to one sliding window and rotates into a groove in the other sliding window when both are fully closed to lock them both shut.

Any help finding these would be greatly appreciated.

ebay and west marine has these. Drill out the rivet and a stainless bolt is used
