PB,
I'd like to get spare joystick shafts/balls for these four sticks:

Is there anyway to tell what size they are? I don't have the machine in hand yet, but I can open it up when I do to get better pics then. I notice you have every color except yellow in 3.5 but you do have a yellow ball, so do I just get the other three colors and an orange one and add a yellow ball to my order?
Also, see how the yellow player is missing a button? Do you have that yellow? I thought it was normal yellow, but it kind of looks a little oragne so I'm not sure.
Anyway, if you know for sure what these are, add them to an order for me and I'll PP. If you are not 100%, at least hang on to them for me until I get the machine in about a week if you don't mind. I don't want to miss out on these joystick tops incase you only have a few left.
This is a dedicated Midway Trog in case that helps. Thanks.
