Newtynewt's are mounted where the original center floor feet should be, notice the second hole in the top of the picture. Someone probably removed them in the last 40 years. All the seats I have ever seen no matter what year had the center feet. Look at the floor and likely there are four mounting holes for the rear in the bed. From what I have seen only two of the feat had seat belt mounts. I actually bought another set so I can mount all four belts to the feet. they are really stout and I don't trust the seat frame.
