I have to agree with Kraig, the 1X7 lever is much simpler than the 1X5, definitely because the brake isn't linked right to it. I also like how much more compact the whole thing is. My only issue with it at all is, obviously, the fact that it's so hard to get to!
Ken, the hydro linkage does not sit inside a tube. I believe you're looking at the steering column tube, which sits directly in front of the hydro control shaft and kinda blocks it. Might be best to pull the whole steering box and column to gain access to it.
