Look at the poor naked Champ...
Are the scales-for-a-bail different to the older solid type, other than a through hole at one end? I guess they don't have the recess for the bushing at the bail end. I'm fairly certain I have some solid scales you can have that could be persuaded to work if you filled that part with something like epoxy or JB weld then drilled through.
You PM me your address, I'll post you some scales. I'll have to have look in the empire of dirt first though and see what I've got.
