Their universal cable kit probably isn't long enough to reach clear around to the back of the axle and you'll likely end up with big cable loops that look ungainly and would likely get caught up in brush/branches/undergrowth if you happen to drive through a lot of stuff like that.
Here's a product that I've long been curious about:

It sounds like it's something to allow you to hook up the cables cleanly with the calipers mounted the way you have them. The owner's name is Blaine and he's a good guy - a little gruff on the phone but don't let that sway you from chatting with him. At $100, it might be a decent option instead of having shock mounts rewelded, new bearings pressed on, etc.
