Sorry, no extra parts!! We did have to call John at Alpine Developments to ask where the roller assembly supplied for the throttle/cruise control cables hooked up to the S/C assembly. You can save some time by putting it on the back of the S/C manifold before you place the assembly on the engine. Maybe they have improved their instructions since my install, in mine they did not even mention how to do it. My advise is to call John if you get stuck. He has been very helpful. Actually, it was about 5 hours from start to finish. Started at 1:00PM and finsihed just before 6:00PM. Started right up and absolutely no problems since the install.
