That part number is actually for a complete starter cable assembly, which consists of the cut to length and terminated cable, an impregnated cloth insulator and a single retaining bracket with an insulating grommet in a loop in the bracket for the cable. The bracket attaches to the forward engine mounting bolt, although some examples show the rear bolt used. Unfortunately the cloth insulator usually disintegrates over time, and replacement sleeves normally do not slide over the terminal lugs.
My Oct 65 San Jose built cars use a C5ZF-14431-A cable which is identical except a second retaining bracket is used. I assume that was to consume excess inventory. The markings on the cables I have show a different supplier, SX, than yours, WCC.
