Re: K20 gear box?

What gear box are you referring to?

Steering gear box?- if so the four wheel drives (K) are different than the two wheel drives (C) and won't be a direct replacement.

The pitman arm for the 2wd is held on with a large nut and lock washer but the 4wd arm is clamped on. The pitman arms are much different as well.
