Generally
Early 1960s have 3 electric motors under the seat that drive the seat so it can be changed in 6 different directions, thus a so-called Sixways seat. This is the bottom part of the power seat switch located on the left side of the front seat, or on the door side depending on the model you have. This bottom part sits inside the electrical connector which has 7 connection pins, it comes with 4 locking clips for mounting in your old chrome frame.
If you have 1 electric motor under the seat, you have a late 1960 and then this is the wrong button, compare the pictures with your old button.
