Ahhh I see! you've finally solved the mystery of those seatbelts for me!!!
Now I've been thinking about this further,
Now I've had either a brainwave or a totally dumb idea. We have bought an Isofix base for our seat as both our modern cars have this, can anyone see the issue with having Isofix mountings installed under the rear seat of my '58? I was thinking if I got the mountings cut from a scrap NB, something like that and welded in the appropriate places so the Isofix base can be clipped into the rear seat?
Would this be possible? Would it be safe? I personally think it could be safer than trying to retrofit rear belts in a car never designed to have them as the mountings would be welded to the chassis, but not being visible won't alter the car visually internally.
What's peeps thoughts on this?
