I'll bet  someone on this list has dealt with the rear speakers in an 82
Westy.   These are in the cabinet above the rear bench seat in a
non-airconditioned  diesel.  I've been looking at the plastic housings that
the speakers  are in and wondering if/how they can be removed.  There are
three  plastic retainer "tabs" on each housing but with them being 28 years
old I  am not inclined to try to force them inward in an effort to remove
the
speakers.  The actual speakers seem to be integral with these  plastic
housings, but I cannot see or feel any fasteners.  There seems  to be an
outer ring of plastic which is molded with the tabs, and an inner  ring just
inside that.  How are these assembled and  dissasembled?  I am needing to
inspect these rear speakers and see  what size they are and if they  need
replacing.

the inner bezel is threaded to the outer speaker cover.  it simply
unscrews.
