It’s too late for my hearing, I’ve lost a bunch of high end and have tinnitus. The boy mentioned that the rear brakes were squealing and I heard nothing.

I whined at the co-worker that does all of our drawings (not really a draftsman but more engineer/programmer) about needing the knobs. His response was just draw them in SketchUp. A bit more whining on my part and he had a functional knob drawn and sliced in 20 minutes. We guessed on length and thickness so it’s way not the right size but it’s a start. I’ll continue my search for a pattern to make a mold from but at least I can get the radio installed and fully functional.
