Enter the "SANWA" plate (holes fit a plate-less JLF) that's usually included with EGRET II's:

Typically, I didn't rotate the joystick so the two holes are the same direction as the plate in the picture, but you can see that the holes match.


The screws stick out of the plate, but they don't reach the panel as the panel's screws are attached to a raised plate already.

As you can see, the stick is sitting pretty low, but personally, I like that. I might try flipping the "SANWA" plate though to gain a couple of mm's in height. Sorry for the pictures, didn't have time to get the proper camera out.
