I've got one stock pair- '89 grey & black vinyl, and, in addition,
a Scorpio or Merkur velour set in mouse fur grey- essentially the same
shade, slightly darker..., IOW, it's a match!

The good:  The Ford's head rest is back & forth adjustable, and the
struts perfectly match the width and diameter of the holes in the
Vanagon's seat back.

The bad:  VW put its stock detent on the rear of the struts, the
Ford's are on the inside.

The solution:  I've used hose clamps on the Merkur leather pair inside
my bus to set the height correctly.  I seriously doubt that they'll
ever jump off the seat back all by themselves.

George/ATL- desperately trying to avoid pulling the fridge out once again.
