66 Charger Interior Door Trim Clips

Good morning! I have been trying to find the exact clips necessary for installing the interior door trim--up towards the window opening (see pictures of clips attached) on my 66 Charger. The clip I need is the smaller clip on the left; the clip on the right is the one I purchased that is too big. According to my measurements, the clip is 3/4 inch wide, 7/16 inch tall, 1/2 inch deep (at the clip inserts). Does anyone know where I can purchase some of these? Thank you in advance for any assistance.

Some other b bodies used the same clips. 67 `s also had the same clips.

Went thru the same thing installing my new door panels. Check Auveco Fasteners, Item # 12134.
