Well, update time. Got the uprights and knuckles back from the machine shop. No slop in the king pins now. Dry fitted the disc brake swap on both sides. Had to do a bit of clearancing between the bracket and the caliper housing, was too tight. Not sure if it was a bracket issue or a caliper issue. Whatever the culprit was, it's fixed. Other than that everything went together as I expected. Maybe this week I can permanently install the swap. I have new tie rods to install and I may as well adjust the steering box while I am there.
I have the C10 shocks I mentioned. I physically verified that the new shocks have more extended and less collapsed lengths than stock so no bottoming the shock out. Boy those original shocks are weak. Dead spot in about 2 inches of the travel and even past that it is pretty light duty. New shocks are gas charged and a lot stiffer. Ought to work better with the Aerostar springs I put in.
