Anybody know if I have to replace the whole cable assembly or can I just replace the cracked bracket part?

Sorry to say, that is a 1 piece cable.

That looks like a Morse 33C Red Jacket cable. They are aweful, for use as a K-plane indicator cable. They have a solid stainless core that kinks if you look at it wrong. I recommend, at a higher cost of course, the "Northwestern" cable brand, otherwise known as "NW" cables. They have a stranded stainless core that slides effortlessly & can be tied in a knot & still slides smooth. The length of your old cable(Morse) is printed in inches, at both the ends of the cable, in white print. Ed

Any ideas on cost and where can I buy a pair of them "NW" cables? Thanks.

I too would like to know where I could get the 'Northwestern' cables.
