Did Chevy offer what I believe is called "Comfort-Ride seats in 65? These are the two part seats, 70/30, driver's side is a bucket with several adjustment levers. They're in a 1& 1/2T farm truck. They look kind of neat, and I was thinking of getting them for my project. However, if they're not a regular option for the Chevys of that era, I'm going to pass on them. Any guidance will be appreciated.
