G'Day Jim, well the guy who I bought one of the Kawasaki ARD's from here in Oz sent me a round alloy "adapter" plate so it could be used on a Honda, but there must be a part missing, because it doesn't fit.
Personally I think I'll just mill a chunk out of the "Kawasaki" mount on the ARD and machine up a round adapter plate that actually fits a Honda. All I'd need then is a really good alloy welder to weld the plate to the modified ARD housing. You don't know any really good alloy welders, do you Jim?
