Button Box Mount

How are you guys mounting your button box to your rigs? I have a standard GT Omega rig and would like to add a button box. I have 5in on both sides of my Fanatec 2.5. Any tips?
Ah, okay, is there a reason for they don't work or did I do something wrong? (off topic sorry!)

Anyway Yasko, Google will find Derek Speare's button boxes pretty easily, they just bolt on to the front so I imagine creating some sort of mount that's similar wouldn't be too hard. Otherwise, I think Ram Mounts get good reviews (never used them though).
Here's another vote for ram mounts as something super-adjustable and easy to use, though depending on mounting and orientation they can exhibit some flex or give over time.
