the kickdown cable i.e.



that, is what controls the secondaries or what? - anyway if that was a dumb question.. here's another

i know the end with the 2 eyelets on it connect to the portion on the transmission and the other end connects to the throttle portion.

what holds the other part on (the one with the threaded end) - on the linkage theres just a hole - and on that part theres no hole for a carter pin or a nut. so how does it even stay on? also.. is it supposed to have slack or no?
