The last one I installed was a Teleflex rack it was a complete set up.It comes with the complete helm assembly rack and cable.It can be installed for the cable to run down the port or starboard side.I called boaters world or west marine it was around $150.00 plus a few bucks for shipping.
To measure for the cable length:measure from your steering wheel and around the side of the boat then out thru the transom.Make sure you dont order too short.Its easy to loose extra cable then not have enough.
