SD, The left side looks fairly straightforward. I haven't removed my chain cover on the right side yet.From what i have seen in other photo's people have had to cut the chain cover to allow the bracket to fit. Of course it all depends on what type of rear set is bought. I was thinking of making brackets for adapting the original/stock levers to fit . All manufacturers have their own dimensions so making a bracket to suit them all would be quite an undertaking. At least with using stock controls (which we all have) makes it a lot easier but who knows yet what may transpire once i get my scheming little brain in action.
