Teleflex 400 series cables (includes parts #51, 53 and 54 above) are excellent replacements at reasonable prices, but you need the plastic end-pieces from your old cable, or new pieces (Parts #41and the little parts that attach to the ends). They are sold in increments of one foot, and it’s important they are the right length. Several places sell them. If you have the style control box that is a few years older than the one shown above, the cables and related parts that hook to the motor are all the same. Below is a link to a place I have bought from:
