Ok, no photos so I will do my best to describe the issue, I will post a photo tomorrow morning when I get to the hanger.
The outside seatbelt attach point (think right for the right seat and left for the left seat) is extremely close to the fabric covering below the door frame. I am estimating the distance from the fabric to the seatbelt attach sleeve (goes through the seat support tube) to be 1/16 to 3/32”. Even if I had had the foresight to put the bolt in before covering it would still be in contact with the fabric.
Possible solutions:
1) Make a really nice covering job look like crap and poke a hole in it, install the AN4 bolt and patch over the hole. There would very likely be a protrusion even if the head of the bolt was shaved down a bit.
2) Find an appropriate bolt (think metric possibly) that is just a bit larger than the AN4 and then thread the bolt sleeve so I could attach the seatbelt to the inside of the tube and not have any protrusion out the side. The seatbelt bolt is about shear, so this would in no way hinder the strength.
3) Use an adel clamp and locate it below the bolt sleeve and subsequent welding which would stop any possible slide up the tubing in the case of extreme stress on the belt system. I have doubts if this would pass inspection, but I am just guessing. Note: I am attaching my retractable shoulder harnesses to the cross tube above and behind the seats using an adel clamp.
I have spoken to Mark G and he liked the idea of threading the sleeve, he is going to check with the factory about the sleeve wall thickness.
Obviously many of you have solved this problem previously, so I am looking for a good solution.
