I can't remember the thread but someone manufactured rear seatbelt mounts using the framework from a van seat.
I saw the attached on ebay which has three van seat with seatbelt mounting intergral to the frame so they can be cut to fit the forward facing seat configuration.
i'm in the middle of moving so can't take on any project like this but looking at the buy it now price it looks a cheap deal.
I live in Southampton so could pick up and store for a few weeks if need be.
