In all my cars, I have changed the old type static seatbelts to the later type automatic ones.
My 240 is fitted with automatic ones in the front and static in the rear.
But I would like to fit auto in the rear bench as well.
I am mostly using the SECURON seatbelts but I am afraid that I will have a problem with the available space for fitting them in the rear shelf.
has anyone fitted automatic ones in the rear? And what type? Any photos would be more than welcome here
Cheers,

you could try to fit XJ-6 rear belts used in the Series 3 (1980-1987). The retractable shoulder unit or "box" is small enough to fit.

It is possible your car is already factory-ready at the rear parcel shelf to accept the threaded bolt for the retractable shoulder unit, being a 1967.

my 1965 S type is factory-ready with a welded nut and reinforcement plate under the rear parcel shelf. Also at the B pillar, it is shoulder-ready.

or try Andover for custom made belts, but I bet the XJ-6 rear seat belts would work.
