Q: It has come to my attention that a Sanwa Dustwasher is not effective with the one that came with the Crown. Is there a dustwasher that is compatible for a Crown ST for sale with different colors?
A: You could try using the conversion shaft https://www.focusattack.com/crown-jlf-conversion-shaft/ this should allow you to use JLF products such as a replacement balltop, a battop and dust covers but not the shaft covers. Installing JLF-CD shaft is not recommended due to small diameter of Crown 303-FK joystick body where shaft resides. JLF-CD dustwasher is compatible. (see the "important" tab on the conversion shaft product description).
