Installing Shoulder Belts

I just purchased shoulder belts (at Corvettes of Carlise) and they are being re-webbed by Ssnake-oyl.

My Question: Correct location of the Seat Belt Bezel on the back of the seat.

Can someone supply the following dimensions: from the edge of the seat to the edge of the bezel, from the top of the seat to the top edge of the bezel and from the top edge of the plastic seat back to the bottom edge of the bezel.

I have the new front seat trim with should belt opening.  Inspecting the opening in the seat frame and the guide it appears the seat belt is guided downward after passing through the frame.

Any data would be of great assistance.

Thanks
