74 cuda seat belt part number needed.

[Ohiowoodchuck]

I got a 74 cuda with the seat belts in the rear quarter panel that come up thru the rear interior panel. Can anyone tell me the part number for the trim piece that covers up the square hole in the rear panel. I looked thru my parts catalog and it doesn’t show the seat belts like that. It shows the older two piece design, for the front buckets. My catalog is dated November of 74. Hope you guys can help.
