The biggest issue in removing & fitting the dashboard in old Maruti cars is that our plastics become hard over the years due to the heat cycles (Extreme heat from sun when car is parked, cooling from AC etc) So if you are not carefull you might end up with cracked Dashboard (Mine has cracked in quite a few places).
@ RPM2500:
Do not remove the dashboard if your car is over a decade old. It can be a major issue to fit it back properly without damaging it. Also store all the screws carefully, Do not remove any AC hoses (air passes through these plastic pipes behind dashboard)
Last thing: Confirm if new spares are available for your car dashboard, in case something goes wrong with this one.
OT: Dashboard prices are insane, considering the fact that MGP stores have no supply of small fittings on Dashboard.
