Grigg, Thanks for the info. Any chance you would have some of the older stuff laying around? I would be willing to send out some templates so you can compare.
I will be pulling the wheels off my 46 2-ton in the next week or so to take a mold off one of the wheels for a project I'm working on. I plan to blast and paint the wheels while I have them off. At that time I can take some more measurements of the spindles, hubs, etc. I won't be able to measure kingpins, but maybe the rest of the measurements will get us closer....
