Another westy owner with the OEM threaded housing contacted me off
line.  So, I quickly went out and popped my speakers out before the
silicon dried.  this is what I did.

I removed the two large philips screws from the bank of the air
conditioning cabinet.  From the front of the cabinet, I slid the
rings through the hole making sure that the speaker wires came
through the screw rings.  Then I put the speaker in place using
masking tape to hold it there.  Next I went to back of housing,
reached way in and was able to thread the retainer ring onto the rear
of the speaker.  Once tight, I returned to the front of the speaker
and carefully used a pair of large needle nose pliers opened wide to
turn the speaker a 1/4 turn or so to tighten up.  I did take care to
remove all the silicon so that getting them out won't be a problem in
the future.

Here's another tip from this guy.  The speakers are glued into the
grill/threaded housing so if you want to retain the OEM look like I
do (no screws), you can find 3-1/2" aftermarket speakers and glue
them in place and then add a subwoofer in your underseat compartment
if you like, just like my helpful firend did.

Since I destroyed my original grill/housing/rings, I'm still in the
market for two OEM speakers with the threaded housing and retaining
ring.
