I’ve used an 09 with the old box and I just had to put the old Selettra Ignition (Stater) I think if you put the 09 Stater on the 08 you need to grind a tap in order for it to fit. I am talking about old one with the starter box. you can also get the old one with the keystart ignition. not sure if modification is needed for that one.
Jim Russell should be able to give you more details. also check the old forum archive.
