i have a whole box of headrests
somewhere in the barn somewhere....

anyway there are little spring C clips in the black headrests sockets.
lookin the slot.  pushthem out with a small flatbladed screwdriver from the
side that you can see the two tips of the circlip.  wear safety goggles and
hold your hand over the other side as they have been known to become
projectiles  when they pop out...

3)   This one is just cosmetic.  Does anyone have a source for this
headrest  in black/gray?  Secondly, any idea how to remove these?  Mine don't  seem
to  budge.
