folks, i installed a pair of adjustable grey leather headrests in my vanagon
tonite, they were from a '86 Merkur Xr4Ti..and they fit great..  now i can
actually adjust the headrest to actually support the small of my neck instead
of pokin me in the back of the head like the non- adjustable stock vanagon
ones..

here is what i did.
-remove vanagon headrests (fyi, theyre in perfect shape, grey, and for sale)
remove circlip and pull out
-remove the black headrest sockets (pry out w/ big flathead screwdriver (make
sure the plastic is warm)
-take a mat knife and trim off the 2 "keys" or raised plastic ridges  that
run up and down the shaft of the headrest socket.
-re-install the sockets w/ the flat side of the circlips facing eachother.
-Merkur Headrest slips right in.. you can now adjust the headrest up and
down, as well as forward and backward.
simple to do, and no more sore necks on long trips!
