Yup. There are visual and functional differences though. Functionally, they make with and without sway bar versions. '65-6 was one sway bar version and '67-72 another. They interchange, but, the sway bar bracket is slightly different in appearance. The lower bumpers changed too over the years, but, they're a bolt-on piece and can be changed. The welded in plate for them changed in appearance over the years too.
