I did it on my Stinger 1 but I don't know for sure if the Cobra uses the same guides. If they are the same or similar, be sure to leave the plastic bearing protector on the new guideway. As you slide the assembly onto the rail the plastic protector will slide off the back side. Otherwise, some of the tiny ball bearings will fall out. Don't ask how I know this.
