Tom, the bodies of the adjusters are nylon or something like it.  They dry
out and get very brittle, impossible to  to remove and reuse if replacing
the whole headlight unit.  They go into the mounting hole and then twist and
snap into place.  They are not designed to be removed even though several
people have reported that they have been successful at that.  But when older
they break just looking at them.
