Tony, list

I need some help on instrument claster disassembling.  I am afraid to break
something.
I took off hinged cover with PC board. I took off plastic housing. What is left
are gauges mounted on white thick plastic plates and these plates are attached
to some board which looks like bigest PC board  in the cluster (the board into
which bulbs are inserted).  There are some small boards are fixed here and
there on this big board. Like board onto which LCD is attached (shall I remove
this small board to service some contacts?).
What is main board there?  So far I don't see square contact posts. Shall I
detach temp gauge and odometer?
