Slight fookup on my part I misunderstood the wording in the document I was reading which said 2 point belt. I assumed this meant lapbelt but what it actually means is a diagonal belt going over one shoulder and fastening at the hip. but not a lapbelt..

and the 87 year was rear seatbelts. Just goes to show the internet isn't always right..
This should clear things up. It's the guide to MOT testers for seatbelt installation.
Seat belts and anchorages:
The condition of every seat belt fitted to the vehicle will be tested. This includes front, side or rear facing seats and includes child restraints/seats and disabled person belts. There must be no cuts in the webbing anywhere, the stitching must be sound and buckle arrangements must work properly and be free from fractures. Recoil mechanisms on inertia reel belts will be tested with the seat unoccupied and must recoil fully. Couplings must release under normal conditions and when loaded by pulling on the belt.
The inertia locking mechanism is not tested and is not required to work for the purpose of the test.
The minimum fitting requirements are complex:
Anchorage points were required for front seats in vehicles first used from 1st January 1965. From 1st April 1982 anchorages points were required for every rear seat (Construction and Use Regulation 46).
Prior to 1st April 1981, cars must have at least a two point fixing belt (one which restrains the upper part of the body but doesn't include a lap belt) in the drivers and specified front passenger seat.
From 1st April 1981, the drivers and specified front passenger seat must have a three point lap diagonal belt (static or inertia reel). Therefore vehicles first used from 1st January 1965 must have seat belts in the front but the type depends on year (Construction and Use Regulation 47)
From 1st April 1987, rear seat belts must be fitted.
