Brake handle should be supplied with kit. Here is a picture of mine. I welded an extra piece back to frame to stiffen it up, did not like the fact that bolting through the fiberglass was going to be the stiffening factor. Cables can also be dependant on which type of rear brakes you are intending on running.
