Removal of the ashtay assmbly on a 210 chassis does not require that the Radio be removed. If your remove the radio on a 99 model be very carefull not to kink the fiber optic lines tighter than aprox 3 in radias.
To remove the ashtray first lift the shifter trim with a thin plastic wedge. A credit card will also work. Then pop the shifter wood trim sraight up using a suitable wedge type of tool. Carefully as the wood is easly damaged. Once removed there are two blck headed screws that hold the ashtray in place . Remove these then rotate it out and up. Good Luck and have fun.
