Question: Cutlass Pickup Covers & Knobs

Does anyone know if the plastic covers that come on the Cutlass pickups are the same spec as anything else you can buy on the market, or are the dimensions proprietary to Music Man? I just bought a used Cutlass RS HSS which I can’t wait to receive, but I’m already thinking about customizing it a bit.

Same for the control knobs – are they the kind you can pop on and off with force, or are they screwed into the potentiometer shaft like the JP model knobs? I’d probably end up changing these out as well.
