Contrary to rumor, I was not smitten with lightning as I committed this blasphemy

I wondered if this would work, and it did:
The parts-

Drill 4 holes, right in the mold marks of the leaf switch plate as it turns out. Drill them slightly smaller than the screws so they can cut threads into the plastic. This also allows a degree of adjustability to tweak the angle of the sensor over the magnet.

4 x 1 1/2" 6-32 machine screws and nuts-

A blob of superglue gel on the magnet. Get it centered on the shaft end before it dries. Mess up? Pop it off, scuff, repeat. The magnet to sensor clearance is very similar to the original U360-

I've tested a few games so far, and it works great, and let's face it, feels much better than the stock U360. My grommet is brand new, so it's a little stiff, but damn, I like it a lot. Original arcade feel with Ultrastik programmability, and no microswitch clicking. Plus, if I get leaf switch urges again, it's a cinch to reverse.
