What type of windshield trim clip am I missing?

[Crown of 66]

Guys, any assistance appreciated. See photo of my 66 Imperial Crown windshield trim

. Why is this trim loose? What type of clip am I missing, and any clues where I might find one? Thank you!

the piece on the right is slid under/into the left piece and should then press into place
