I assumed my car would at least have the holes in place to accomodate some rear seat belts but it doesn't. Does anyone know if they actually do have them somewhere(1967)? I was looking around under the fuel tank area and under the seat, but nothing.
 
Otherwise, is anyone else able to take a picture of their mounts/seat belt holes for the back seat so I can figure out how to sort mine out.
 
Will I need to have the engineers approval if I do fit some mounts in? Or would I have to take it to  professional installer?
 
I'm only really needing the middle lap sash.

Thanks man, the top pic is blurry but are they holes or lugs to clip the belt to?

there very simple there just an eye bolt and the seat belts clip in  with a clip like on a dog leash. when i get back home i can get more closer pics but im at home for christmas till the 1st

I had some rear belts in my old thou (RIP). someone had just drilled holes in the follr pan, and put bolts thru. They used big washers on both side to try and give it some strength.
 
Dont know how effective they would have been, but it was something.
