I've got a set of three-point seat belts that I pulled out of a 74, the last parts car I had, about 15 years ago. I didn't think they were original, but a friend who's owned several Cudas tells me that 3-point belts were available in 74. This doesn't explain why there are no pentastars or Chrysler part numbers anywhere on these things.
He's not right, is he?
