Boat Buzz

Ok guys I have exhausted my seach for a new steering cable for my 1970 Chris Craft XK 19. This is a rack and pinon system that has a round cylinder about 1 1/2 inches in diameter and about 16 inches long that has a round cylinder inside oh it with teeth on one side of it that the cable is attached to. The Cable is blue and has the markings at one end of it " C2 MARM-20ft" If any one knows who made this steering system of where I can find a cable please let me know. I have spent hours trying to find info about this system.

I am just about finished with the complete restoration of this boat. I will have pictures very soon.
Thanks everyone,
