DING! and the winner is....
2572070 to 2593704 is 2002 Right hand drive (USA) Model 71. Production between April '71 and Aug. '73. One of 21,635 made during this period. Euro cars have flush front turn signals, no side marker lights and rear plate lights are in the bumper and not on the rear bodywork. My 1602 is Euro model, there are plenty of pics around here somewhere.
Dealership will have nothing on this but ask Mike in your parts department, he may know the car.
Good luck man.
