One more quick question before I head out to get new speakers for my '85
Westy.  I noticed that the rear speakers (in AC cabinet) can rotate freely
in both directions, so I know that they are not screwed directly to the wood
panel.  My question is, are these speakers simply held in with some sort of
spring clips, or is there hidden hardware in the back to hold them in?  If
there is hardware that needs to be removed, what is the most painless way to
access this area?

                                                Thanks in advance.
