I guess they are the set screws this talks about -
67. SPROCKET ADAPTERS: The sprocket adapters must remain stock, within the stock dimensions, steel thickness, location and configurations of the original, as currently delivered by U.S. Legend Cars International
Set screws for the sprocket adapter nut are permitted. Lightening the sprocket adapter for weight savings in any way is illegal.
I don't have them and don't have any holes for them. Can someone tell me the size, length, etc of these. It sounds like a good idea and can't be too hard to drill a couple holes and tap them. Also, do these set screws have locking nuts on them or are they just little bolts?
