The threads I mentioned are under the knobs. The view in the picture is obstructed. Even with the knob removed the flat washer and jam nut would probably block it as well.
Pots are stamped "A" for audio taper and "B" for Linear. You can use any value pot you have on hand (in reason) I keep meaning to make some of these for my Moogerfooger rig. It too easy of a project not to.
Another cool trick in a 1/4' TRS plug with a LED soldered between the Tip and the Ring. It gives you a visual when your deciphering CV outputs.
