OK, I understand that the older wheels are hub aligned.
True
But the later wheels are stud piloted so do not require a close tight fit on the hub.....
False
Both new, old, and all wheels with 10 lugs on 7.25" bolt circle are hub piloted.
Don't be confused by the nuts that appear to be the stud piloted type, because they only fit he clamp plate they have nothing to do with centering the wheels. The wheels are not chamfered to be stud piloted, and I don't think you'd want to.
To answer an earlier question about the bushings needed to use late wheels on early hubs;
Yes they could be welded into the rim and bored out again, but that is a fair amount more work than necessary. A simple bushing retained by the old clamp plate is simple and reliable.
Swapping to later axles with the larger hubs is another option.
