The spring clip can slide either way but I find it easier to push it toward the front of the car. The clip has a ridge on it, which you can use as a push point.
I got my cable from Pantera Performance in CO and it looks identical to the original factory cable. There is a telescoping end on it with a spring that goes around the outside. The cable part is thicker than your cable. Notice that I added a second spring as a safety.
