Hi Kevin, are you looking for the cable or the handle ?
if I'm not mistaken the handle comes from a Ford Fiesta (most probably a door handle).
For the cable, I guess you can put anything that has the right dimensions. Mine is pianocord type, but I'm not sure it is original.
Anyway, 2 times in the last 19 years, the cable broke at the fixation to the handle. Fortunately, I was able to fix it without changing anything, but I was worried it could eventually brake at the hood level, which would make it an ordeal to open the hood. So I have now a second stainless steel cable acting as a backup solution in case of issue on the main cable. The spare cable has a simple ring at the end to pull the cable easily.
