please help identify these bucket seat.

I purchased these seats for my son's 67 Dart. I was told they were for a 68 Dart. I've been trying to find new covers and it appears that they may actually be 64-65 Barracuda or Valiant seats. Any thoughts? I'm not concerned necessarily about the car being original, I just need to know what they are so I can get covers that fit. what other year covers would fit. my biggest concern is getting a rear seat cover to match the new fronts without having them custom made. This is my 16 year olds daily driver and looking for the best , low cost option to dress up his interior.

On a side note, yes that is an auto console with a column shift. we are slowly collecting parts to switch to a console shift. I removed the auto plate that has the gears listed on the console and replaced it with black plates. it doesn't look to bad and now he has more storage and an extra auxiliary power port.
