Our Training wheels are ready to install on dummy spars.
I turned a shoulder on the castellated lock nuts, then TIG welded in place, the mounting plate pivot bracket was ground off, repositioned and re-TIG-welded in place and the handles were cut down and re-TIG-welded to a size that allowed your knuckles to clear the fuse. There isn't much load on the wheels so the short lever arm of the handles should not be a problem.
