With several model changes happening at the end of 1967, I am trying to find out what the correct seatbelts are for my 10/67 build 1968 911L. There are no anchors in the rear wheel wells from other's photos that I can see...and with several types/brands, etc... being offered for sale, would like to know what my car is supposed to have.

The Dr. B Johnson book didn't have anything specific to seat belts, only seats, and I don't know if/when there was a change or cut off.

Thank you!
