Guess what. Mine 67 RS doesn't have retractors... and yes it has the chrome doohicky. I am 100% sure they are the original belts.

The seatbelts are model 47 with a C 66 date code on them. I have the deluxe interior with the deluxe belts.

My belts have this cover on the end where it mounts to the car, its like a rubberized sleave that covers the bolt. I couldn't get an accurate measurement with the chrome retractor doohicky and my belts are kind of ravled so I don't really want to take the doohicky off, but it is approximately 19-1/2 inches from the points you show and 20-1/2 inches from the mount point at the top to the bottom end.

If you need a more accurate measurement and pics, let me know.
