You guys are right. 1/2-20 thread. I corrected it. Making little verbal errors while thinking about the complexities of wheels, tires, hubs, clearance and determining what I actually have part wise, I did get a lot done today decision wise and actual progress. Talked to the wheel guys and the adaptor company. One ride control air bag installed and will do the other side in the morning. Will get the wheel adaptor for the front hub ordered is the plan.
