[V8] Front seat headrests

[Ed Kellock]

I am disappointed to find that the headrests in my 93 were "updated"
along with those in the C4 chassis cars.  They are flacid and are set
further back in the seat.  In my other cars, I never actually use them
to support my head, but I do enjoy the ability to steady my head
against them at times.  This is not possible with the newer style
ones.

Would anyone have any idea if the seatback from an earlier style seat
could be swapped in place of the newer ones?

TIA,
Ed
