I want to put a forward facing seat in the back of my 90, it will be possible to easily remove this by pulling out a pin along the side of the seat where it mounts to the top of the wheel box. I do want a seat belt to go with this and it will have to be a three point mounting.
Problem is that I don't want a seat belt anchor permanently sticking up in the middle of the back of the l/r, especially when I have the seat removed and want to fill the back with boxes or diving cylinders. I was wondering about putting some sort of anchor ring, or even better a recessed anchor plate, onto the floor and then fastening the bottom stem of the seat-belt to this when needed with a maillon. Climbing shops sell these high strength chain links, they also sell high strength 'hangers' which are designed for shock loads - might be possible to modify one of these??
Any suggestions for where to obtain a suitable anchor point or ring for being bolted to the floor? Has anyone done this?
Thanks,
M.
