Hi everyone, so I made my Mame32QA joystick 22 years ago and got into Saint's book.

I just pulled it out of the closet and was going to do some work on it.
It's got an original ipac-2 ps/2 version and replacement Slikstick aluminum bat tops and probably their shafts. I was interested in seeing what a ball top would look/feel like it but everything on Amazon these days is M6 hole size which is too small for the Slikstick shafts. Does anyone remember if they went their own way w/ sizing or did they mirror the Happ Super's 5/16" (if that's what they are)? Where can I see some options for tops at those shaft sizes these days? Thanks!
