remove the radio by using the special tools (prongs) that slot into the holes either side of the radio (about $20 from Bursons). Remove ashtray and 2 phillips screws behind it. Once radio is out there is a screw either side of the panel. remove these 2 screws.
Then..........put your hand in where the radio used to be and yank on the panel until it comes out, there is approx 6 steel clips around the panel that clips panel to dash.(these are the things that rattle).
If you just want to pull the panel out partially then this is ok, otherwise to totally remove it you have to pull out the glovebox, disconnect heater control cable, remove vacuum lines of control switch and heater valve, unplug heater fan switch & demist and a/c switches etc. Not impossible but a bit of stuffing around
but BE WARNED! when you partially pull out the dash, be very careful that the steel clip on the lower LHS doesnt SCRATCH the dash pad!! Put a rag or something there to stop it from rubbing :s6:
