One of the straps broke on my car today. I called my local auto parts stores. Turns out they are a "Ford only" part. I called a local dealer. Turns out they are sold per side. More than a $100 for the left side and $72 for the right. Fortunetly I only need the left side, unfortunetly, I should put the right side on too as it is in bad shape. Any idea where I might fine these cheaper?
