You should be able to tack a new one on where you removed the old one.  You could dangle it from short leads if the footprint isn't exactly the same and you could connect those leads at the header itself instead of where the pot used to be. 

You could also just try connecting pin 3 to GND as you may get an acceptable display with 0 Volts at pin 3. 

You could also try fixed resistors as a voltage divider.  Start with 1K between pins 1 and 3 and 10K between pins 2 and 3.
