Where can I buy the g27 shifter module?

[donghe08]

I broke the resistor while repairing my g27 shifter, so I googled and found that you can't buy the resistor, but you can buy the internal module. However, when I tried to buy the internal module, I couldn't find where to buy it. If anyone knows where to buy the internal module, please comment!

How exactly is the potentiometer broken?

These look like CTS Electronic Components 963280 potentiometers... but they aren't made any more.
But CTS Electronic Components 251B12T104A2NB look very similar but don't have the little green plastic lug
