Seat belt conundrum. I would like to fit reasonably priced seat belts to my PV444. My chassis number is 137113 and I have some early mounting points on my B pillar and presumably under the rear seat as per this technical service bulletin:

But it appears that retrofitted modern seat belts will be incompatible with these mounting points. For the outside mounting point, it appears that I will need to install mounting points on the floor or on the inside of the sill just at the bottom of the B pillar. Doesn’t seem to be any access on the inner sill.
It looks like I can get access to the underside of the transmission tunnel.
Looking for suggestions on course of action, including practical advice on hardware.
