Part # for 3-Point Rear Seat Belt Guides

[1989Carrera]

Can anyone provide the part number for the 3-Point Rear Seat Belt Guides for my 1988 Carrera?

I've spent a couple of hours a day for the past several days trying to find part numbers for these. I found #911-555-627-00-01C in PET and the description is Trim cover, black, for rear three-point automatic seat belts", but pictures of that part number are not what my 911 has.

Attached are pictures that shows the kind I need.
