I tried searching but couldn't find what I was looking for. In the process of getting a new front floor in. car bought in pieces so I was looking for the seat belts but didn't find any was woundering how they mount in a 73 chally hardtop. And we're they an option in Canada I think it wasn't required to wear in 73. The car I have is very low optioned so that's why I ask . just want to no if there are brackets that should be welded in or anything like that
