So I have an 07 Sportster 1200C with custom bars, and I'm planning on putting these on it:

11 inch rise, 8 inch center, 7 inch pullback. I know I need to extend the cables, and was planning on getting a Novello kit, but does anyone know (or want to help me guess) at what length kit I should get?

I want to put the cables/wires inside the bars, too. So I'm guessing I'll need even more length than just the 11 inch rise. My first guess is around 16-18 inches. The stock cables already have a bit of slack to them.
