Desolder the pot and measure resistance of pins 1 and 3. That will be all you need to find the correct replacement as they are simply voltage divider devices. Pin 2 the wiper divides the voltage drop across pins 1 and 3. If the resistance between pins 1 and 3 is open circuit then you'll have to find another way to determine the correct value for total resistance.
