Early A body bucket seat interchangeability

Just about any seat can be modified to fit, but, as a bolt-in....the '67 up ones won't. '63-6 might, but, I don't have any first hand experience with that conversion. '63-5 are a slightly different width (wider) than the '66 seats due to the first year console option in '66. You will probably have to drill new holes for the inner seat tracks. I don't know if they come with both sets of holes in a '62 model. I would bet that it doesn't, and probably not the reinforcement plates either.
