The Crown CWL-309MJ, also referred to as a MakeStick 309MJ, is a modified Crown lever that features a shortened top grommet that is “JLF” compatible. I have yet to test fit this in a Panzer Fight Stick 3, but it is mountable in the standard Panzer Fight Stick 3. I do have some concerns over the overall height of the lever body fitting in the 1.75″ of internal space in the Panzer Fight Stick 3 (lever spacer installed), but similar Korean levers that fit the “JLF” mounting pattern do work in the Panzer 3.
These levers WILL NOT MOUNT in a Panzer Fight Stick 3: Korean Edition. If you want to use an authentic Korean Lever in your build, I recommend using a Crown CWJ-303N lever or a Myoungshin Fanta Lever, shown below.
