its easier than installing a new motor as well. takes about 20 mins to pull and install if u going slow and u can use any cable just grind off the little end till its perfect.
you might wanna look at the surrounding pieces of your cable to figure out why it was fraying, is it rubbing? was it not installed straight? did the nub get jammed? was the spring right? is there an elbow?was it rough on the inside of the elbow, is the elbow aligned, with pull? am i twisting too hard to go faster, whats gonna break next? etc, etc, etc
