daniel,
Sorry but you are too late... I had a tonneau cover for my 2003 Sport Trac that would fit your 2005 model that I was selling cheap. It included the LeverLift EZLift and the EZLok electric lock conversion (I made and sold the LeverLift Company) and also included a Ford Rubber bed mat, a bed extender, and a few other Sport Trac accessories,... All for only $300. I did not want the hassle of shipping and wanted someone willing to drive to Waco, TX or at least meet me within 100 miles. Nobody was interested then?? I guess it was due to the economy.
Anyway, good luck with your search.
...Rich
