I have an easy street air management system for sale on ebay right now. It's an electronic air controller (digital) that would control all four of my air bags independently. It comes with (2) 12 volt air manifolds. They cost new $263.00 each if bought seperatly. I'm sure you guys could think of some really neat things that this kit would enable you to do!! Anyway, here is the link to my ebay item -
