Hopefully one of these mustang "gurus" on here will chime in and be clearly specific on this one.
However, I can tell you no, they are not the same. There is a considerable difference from the 65 -66 to the 67 -68.
I have both a 66 and a 68 and they are different as night and day as far as shape is concerned. Pick up one of the mustang supply catalogs ( CJ Pony Parts, Mustang Unlimited, etc.) Most of them have plenty of photos showing you the various seat shapes and options let alone the various upholstry.
