One of the quickest, cheapest and most effective mods I’ve done. The seat belt now pulls out smoothly, the inertia locking works perfectly (probably for the first time in its life), when you unclip it retracts smoothly back into the reel and doesn’t get caught in the door causing damage.
Obviously any changes to the seat belts are at your own risk.

Reasonable price and good service.

..... They have a range of flat or 90 degree extension plates that would do the job.
Cheaper than the rose joints?foot2firewall said:
..... My question is - would attaching the runner with a nut and bolt to the extension plate be an MOT failure or not?
I've had two MOT's done since I fitted the rose jpoints and no query.glenrobbo said:

If you have any left over can I buy a pair of bolts & washers off you? 
The seat belt assembly wouldn't have been supplied specifically for TVR so the bracket would have originally have been designed to be bolted to the 'B' post just above shoulder height in the normal way. So even in its original TVR fitting it was not working in the way in which the manufacturer designed it to.
Assuming the way the bracket is mounted vertically in to the rose joint, or modified bracket, is able to take the load (which it should be more than capable of), then the force is transferred back to the mounting point in exactly the same (horizontal) plane as TVR fitted it.

As a non-engineer it seems to me the weak point will be the weld on the steel loop. The bolts should be capable of taking tons of strain. I can't do the maths but I'd imagine you'd have to accelerate, say 12st, at a considerable speed to a point where the force would sheer the bolts (maybe one of you guys could work it out?). I'd also guess that in these circumstances the whole mounting would be ripped out of the body before the bolts failed and the other injuries sustained in an accident at this speed would make the whole thing academic.
As someone else has mentioned, the revised mounting point means the inertia reel can actually retract as it was designed to do so making the belt much safer than the way TVR installed it.
Fair point about advising your insurance compamy though.
