I did that on my 69 Dart years ago. You need to feel your seats and make sure yours have the holes in the frames for the hardware. Not all of them did. But I remember it wasn't that hard.
the two headrest bezels screw into the top of the seat with two screws each. are you saying that i might be able to feel the hole for the headrest shaft and the two screw holes in the seat top frame under the seat cover?
i'm guessing you have to remove the seat cover to be able to install the plastic headrest shaft guides. is that what you did?
