I pulled the front steering linkage and the steering box, just to clean the encrusted gunk off. The steering box was natural cast finish with an aluminum cover and a pink paint daub on the spline where the steering shaft mounts up.
Dodged a bullet here! Check out the steering box bolt in the center. I used PB Blaster to loosen the bolt but it still took an impact gun to get them loosened. I would loosen, then tighten, then loosen repeatedly, to rock them free. Looks like the center bolt came out just in time. I was surprised it didn't break after seeing how much was rusted away.
