I wish I could help as I have a set on each one of my Rockets and one in the box for the Rocket I am going to revive and put back on the road. ( broken crankshaft and broken valves
) Anyway they are all pre roadsters so I did not have the particular master cylinder problems. If it was the bolts not being long enough I would just scoot on down to the store and pick some up. Keep the length handy so when you call Carpenter you can let him know and maybe he can include them in the kit. Your the first I heard of having problems with it. Maybe you should send a Message to steel he has a Roadster with Bob's pipe he might have some input that would help and could confirm if he ran into the same problem.
