This might not qualify as an option but maybe an idea...
I made these wheels for my HD back in the early 90' using the following assembly principle:
Left hub->centerdisc->wheel rims from Compomotive L and R side -> Right hub.
This approach of course requires the required machining equipment and skills, but it
gives you the option to make the wheels exactly as you want them.
Another alternative would be to use wheelblanks (see
www.allamericanwheels.com)
If i would make another set now this is the way i would go.
Take care...
