How do I change my trackball?

[dprush83]

I bought a new blue 3" trackball to put in my control panel, the trackball website said any 3" ball can replace the default white.  When I take the trackball unit off the panel there is no way that I can see to open it up and swap the ball....any links to how to do this?

You need to tell us exactly which model you have or at least put a picture up here for us to see.

Thanks!  I'm not sure the type, but here are some pictures:

i'm not sure what model that is for sure...but i bet someone does.  there should be a few screws on the bottom of the unit that allows you to open it up

Ah, there were hidden screws on the bottom....looked at it about ten times before I saw where they were.   

Thanks severdhed.

Well, you already figured it out it.
But that's the one I figured you were talking about.
Seems like there was someone else not very long ago that had the same problem.
