I replaced my front pads and rotors today on the '10 MKS Eco and all went well. The rotors just came right off which at 103K miles I was pleasantly surprised. But on the driver's side caliper there was only one of the spring clips present that hold the pads apart. I've searched a few parts places for a replacement with no luck. Anyone have an idea where I could look? I've tried Rockauto, Car ID, Summit, Oreilly's and Autozone with no luck. TIA for any help with this.
