In this case I feel certain the plastic strip is broken, the antenna
will go up but not back down, unless I push it to where the strip
engages again. I'm still looking for some more detailed
instructions. Removing the black flush mounting for one thing, and
then there is supposed to be a wrench the fits over the existing mast
and removes some "nut" on the antenna assembly thereby releasing the
mast and cable.
Anyway, John Smith, I may take your advice if nothing new turns up.
Looks like a dirty job, I did it on an '87 once, that one mounts a
little differently than this '95 car but I could suffer through it.
