Thanks guys, I was starting to think there might be a way around not removing the ball top. It seems mine *had* a set screw in it but now theres just a tiny hole on the lower portion of the ball top where it used to be. And it's definately a 4-way stick.
I'll probably take another stab at dismantling it this weekend. I appreciate all the info! Does anyone have any recommendations for a good silicone spray to use on it after I get all the grease cleaned off, is WD-40 fine, else I have some stuff out in the garage for use with the car. It all seems the same to me, but this is my first arcade cab and I wanna fix it up nice ^_^.
