Oh… might as well have bondo’d it up and used some touch up paintEr, slightly smaller than a standard CTS shaft. The two holes for the new pots needed to be enlarged slightly -- used a drill bit as a rasp and gently did it. I was extremely BAD and cyano-acrylated the two nylon pieces into the unused holes. When the bridge pickup was removed, I fixed that blanking piece with nail polish in case I should ever need to remove it.

I was going to suggest those dust/dummy for 1/4” speaker jacks. Can’t find them though.
