If have your original, un-restored headrest, were the plastic bottom covers retained with black plastic rivets, or with screws? One of my original head rest had one plastic rivet and one screw retaining the bottom cover. The other head rest had screws.
After closely inspecting the attachment hole in metal substrate where the plastic rivet was located, there was no evidence that a screw was ever in the hole, but it hard to be sure.
I would like to know which hardware was originally used to retain the covers, and the build date of your car in case either retainer type was used during the ’69 model run.
Attached are a few pictures of the head rest and the plastic rivet.
Thanks,
Dave
