Rear seat belts

[Bentley]

I want to put 3-point seat belts into the back seat of my Trueno, has this ever been done before? Any pictures?

Because I don't think I can register that car for 4 people with the 2-points that are standard. Must have 3-point here in Sweden.. I think at least. Cuz all other cars that got here from other countries has always had to adapt before getting cleared.

I was thinking of bolting the "roller" into the bracket where the interior panels are fitted just above the wheel housing. Plenty of metal there and there's already sort of a premade hole on the interior panel just at that spot that just neads to be opened.


Any thoughts on this?
