Quoted for truth.....
In about a year, I'm going to bump this thread and ask you if you feel the same way about the P.O. and the "deal" you got on this truck.
Most of us have been where you are now.... Buying a new K5 project with stars in our eyes about how great everything is, and how much "good stuff" the truck has. Over the coming months some of that "shine" wears off as you learn more about what's really going on.
That steering setup is a perfect example. You got a truck with "crossover and high-steer" on it, but in reality you will probably end up throwing all of that away (or at least you should!

) to install a safe, correctly engineered solution. You may be tempted to ditch the hydro-assist to save money on the rebuild but there's a good chance that you'll end up with death wobble without it. Even freshly rebuilt D60s will get death wobble, and that D60 is clearly not "fresh" anyway.
Not trying to be a bummer, but that steering is downright dangerous.... Don't play games or shave dollars on something as important as steering (safety). Fix it right and give yourself some peace of mind.
