Can I use a Happ 3" trackball plate with an Imperial 3" ball?

I would like to flush-mount my trackball, but I need a Happ plate to do it. Can I fit an Imperial 3" trackball onto a Happ 3" plate?

yes you can... I did it with the non-flush plate... but the mounting holes are near-standard...

Yes, I used the flush-mount plate.  3" Trackball holes are standardized (size & location).

BTW, my Betson/Imperial TB leaves a little itty-bity bigger space around the TB lip than my happs TB; approx 1/16" diameter difference, so 1/32" space all the way around if mounted perfectly centered.

I kind of figured this was the case. That's why I asked. There's one more part I can order from Bob Roberts! I need to compile a list...

I had to enlarge the holes on my Imperial to use the Happs boltless plate. Not much, just slightly. I'm not sure if I had an older model and that was the reason or if the newer ones also need this.
