shop around before you buy the kit
tick offers a year warranty if they rebuild it, and they know their shit. and it might cost just the same. the level two was almost 700 shipped. figure 1350 for the stage 2 rebuild including the 100 dollars shipping there and the 100 shipping back thats 650-700 for labor. local shops may charge the same.
i'm not reppin them or anything, and i have no personal stake in what you do, but getting it from tick may be the same price, and you are going with a company that does nothing BUT rebuild t56s and has a proven track record, minus a couple people that had catastrophic failure because they don't know crap about their hydraulic system lol
