ebay is good, try richierich on here. Even if you reroute the cables, 2" was max on my Phazer. You want to be able to turn freely. It made a huge difference on mine
On my Exciter I used a piece of 2 x 2 steel square tube that was about 4 inches long or so, and just re-bolted everything back on to the square tube. Its cheap and easy.
As mentioned before 2 inch is the max with stock cables.
