Yeah I went to an 07 SS swing arm but i had the kit on the stock 07 swing arm initially. i had to shave out the belt guard brackets to get the chain to clear but I had no problem with the bolts. They are very close to the swing arm but they didn't touch so i didn't have to shave. Looks like shaving yours is the only option.well it appears 06 and later swing arms need notching for both the chain and the bolts for the rear sprocket.
