Call Dale at Tymar..509-922-8785, hes got a kit thats about as cheep as you could put togetther yourself, which not worth your time to do IMHO. It comes with all instructions. At the same time talk to him about his intake and exhaust systems. The BEST guy in the business as far as I am concerned. And knows as much or more about our trucks than anyone out there.
