Can the seat push buttons be replaced?

Thanks clhyer. My seat is a plain bench and does not have the headrest. And the drivers side has no button and the passenger side has a button that seems to be bent and the outside cover around the button is missing. I just went through this with seatbelts. The previous owner removed the front belts and cut the belt at lower side panels. A FABO member sold me a set from a 76. They were different, but work ok. The button that is there is also chrome. Thanks, Randy
