I was finally able to acquire the prop and mixture knobs, but will just have to paint the the throttles.
For anyone that needs them in the future, part numbers are listed below. Webco used to have a subcontractor fabricate these but no longer does, so they're all out and are tough to come by.
There are prop knobs available overseas, but can't find anymore on Parts Base available in the US in new or new surplus condition (Dodson and Wentworth have used ones though). I managed to grab the last two I could find on Parts Base in the US, but hopefully more will pop up.
There are no throttle knobs available I could find (except for salvaged).
Mixture knobs are readily available from multiple Piper parts dealers, including KRN Aviations Services.
$10 is the going rate for used/servicable knobs (either throttle, mixture, or prop). Brand new (for those you can find) ran me between $3.50 and $15/ea depending on where I could find them.
Throttle Knob, black - p/n: 571-045 or 24049-00
Prop Knob, blue - p/n: 24047-00 (no alt. p/n)
Mixture Knob, Red - p/n: 571-044 or 24048-00
