i was wondering if anybody has a pic of this mod. me and my roomates are looking for some kind of layout to start with so we can make one.

 

If you were to make one, just measure the distance you need, and go with a material highly resistant to bending. You can get fancy with different curves and whatnot, but anything that will strengthen the towers will do the trick. It'll look like any other rear brace. Here's what Kenny Brown's looks like...
