This segment of the modification is complete. The removal of the old CTS were done and the ALPS installed. I did my best with the photos of the process.
The offending pot in it's place.
A close up.

Some measurements, and the marks for the holes.
The pot ready for solder. Notice the holes have been made. A dremel tool.
