Top hold down cables (also known as side tension cables) are located on the outer edges of your convertible top, they are there to keep the top material from flapping or fluttering when driving down the road, they also help keep the top from shrinking up from the side windows as the top gets older. If you notice your convertible top is making more noise when driving down the road or you are considering installing a new top then make sure you install new top hold down cables, it is a small price to pay to know your top is done right. This set of cables is for your 1983-1988 and 1991-1993 Ford Mustang convertible car, these are the side tension cables, they have an overall length of 34-1/2 inches and they are sold as a pair.
