I have never owned or looked closely at a '99 up cobra engine. I have a 2001 GT and the cable mounts to the bracket by pushing it into a square hole and then 4 push clips lock it in. The 1998 cobra has a metal flange built onto the cable and a single bolt holds it onto the bracket. So you '99 up cobra and bullit owners, do me a favor and go look at how your cable fastens to the throttle cable bracket.
