please help identify these bucket seat.

Those seats are ‘65 Valiant (frame identical for ‘64 plus ‘64 -‘65 Barracuda & Dart). So any ‘64-65 Valiant, Barracuda or Dart cover will fit.

The ‘66-‘67 seats have a sheet metal backside but more importantly I beleive they are just a touch narrower to fit the new for ‘66 console that you show in the pic.
So you may have some interference between seat & console but I think some guys have gotten those to all fit in an early A.
