We have really drifted this thread a long way from Shaley's original topic of the TC55. I know the TC55 has a dual kit, valve kit and lever kit. I think that's because that valve is used on other models with a different lever arrangement. It also really drives up the cost of hydraulic remotes. I truly feel sorry for anyone installing remotes these days. My first remote was $250 and the 2nd and 3rd were $215 each. Some people are paying that much or more for one remote these days. Even so, there is nothing out there as neat and clean for installation as NH's kits. That probably won't make spending the money any easier though.
