I Have a set of 69-72 buckets for my cutlass the person i got them from had them re covered without the headrests when i took the old seat covers off i found that the top of the seat frame had the holes in the frame for headrest but on two of the headrest holes were plastic parts that were screwed into the frame. It looks like the headrests go in the lock assembly then into these plastic assemblies which would be underneath the cover. My problem is i only have two of these and the other two are missing. I would like to know what they are called and where i can find them or have them fabricated? I am in Ferndale Mi.
