Exact interchange is '64-'66 Dart-Valiant. Front and rear same, except the rear ones had ashtrays. Fit-function interchange goes back to '60, though the '60-'63 armrests are a different, 1-piece design and a no-ashtray version is used on all four doors (I like those better; they're sturdier).
The longer 15-inch items are for 2-door cars.
