Need rear seat identified

[gforsberg]

Hoping all you die hards out there can help me identify these seats. They are A-body seats, just not sure exactly what era. The black ones are being used for comparison, they are for a 67 Dart. The only real differences I can see are the way the seat back is mounted in the white seats, they bolt in and also the transmission tunnel hump seems smaller with the white seats. Thanks!

Is the black dart seat a concert seat? They are narrower than HT or post / 4 door

It's a hardtop. Pictures may be deceiving, white one is same width

The tan seat has the broadcast sheet in it . That should tell you. The cutouts in the corners of the seat are for 72 and newer seat belts and . Also the seat is held in by bolts at the bottom verses the early years with the bend over tabs. Look like 72-73 seats to me.
