Seatbelt mount question

intresting... but i think you are right, you should have seen it more often even if its in another country. I found this thread.
3 Point Seat Belt Conversion
In that a guy had put a mount almost like mine with some reinforcement and it had past inspection, at least in the us.

In Sweden i could legally drive it wihtout any seatbelts at all since its manufactured before 1970. if you put in belts it must be the factory mounts or you must have documents that the new mounts will hold up to whatever newton or measurement they use. Or if you get lucky and the inspector guy is missing it. Or i know some guys just take it out before inspecting the car. Car over 50 yearsold in Sweden only needs one inspection then its done forever.

But in the end its safety first, so ill see what i will do.
Thanks for the answers so far :)
