I have a Sega control panel that has a non-Sega mount, I'm pretty sure it's a 3rd party panel, but in any case it uses threaded posts, not the raised wings (https://gamesx.com/wiki/doku.php?id=arcade:control_panels#sega_aero_astro_city_v1_panel_mount) they normally used. I have Seimitsu's All In One plate, but it doesn't fit, so I had to make my own P=50 plate.
Unlike [url-https://nfggames.com/forum2/index.php?topic=7483.0]the P=40 plate[/url] I didn't use reinforcement to stiffen the plate - the larger base of the LS-32/Nobi etc effectively stiffen the whole assembly. I also added a space for the internal dustwasher, as some of the newer sticks use them.
