66 Barracuda front seats
On those seat tracks the mounting studs appear to be too far apart for a 64/65 A Body. Just measured mine on my 65 Valiant and the studs are just about 11 inches apart. Also the outer track IS taller than the inner track and the seat is leaning towards the inside when sitting on the floor. Once I tried to fit a set of 66 Dart buckets in a 65 and the stud spacing was too wide (66 was farther apart by well over an inch). For what it's worth, the spacing for the mounting studs from a power seat rack from a driver's seat from a 68 Chrysler Town and Country wagon fits both a 65 Dart and Coronet perfectly.
