I've been looking for the same thing...almost...rack and pinon replacement cables. Did you go into REX or EDDIE Marine sites yet? There's quite a bit of rotary steering parts there...I think alot has been outdated or has been upgraded. If it's for a Schiada try the man himself at Schiada. Google search came up with go2marine.com Go to bottom of parts locator and search part # 100065
