Thanks for your advice guys. Can anyone clarify whether the front discs on the MC18 1989 are interchangeable with the MC21 model? If so is their anything like year models that I should be aware of? There are plenty of MC21 parts in this country but MC18 parts are as rare as hens teeth.

Also can anyone clarify whether the front wheels are interchangeable between these models and what year if they are?

Regards,

Matthew
