Unfortunately, there are so many different airspeed indicators out there we can't stock dial faces for all possible configurations. We include a dial face only for the Self Compensating True Airspeed Indicator. If you have a standard airspeed indicator or a copilot's airspeed indicator, please remove the instrument from the aircraft and have an instrument shop mark your current dial face using the dial face drawing contained in the Option#2 envelope. The aircraft may still be flown if it is in Option #1 configuration.
