Discussion about the Korg PolySix synthesizer

Hey all,
I'm well aware that there is no source for original Korg Polysix knobs (outside of the occasional high priced ebay listing for one or two) thus for my backup Polysix I'm restoring I'm thinking of just replacing the entire set with something compatible in size (ie: what is used for the Polysex mod)
Can anyone point me toward the mouser etc part number that will fit on the pentiometer shaft correctly?
many thanks!

I have a bunch of the original knobs if someone wants to buy them.

Hi, I would like a few, what is the price and where are you located?
