Need to replace another fan clutch in one of my trucks (03"). Was looking at Strictly Diesel's web site, they have a kit that replaces your OEM fan clutch with an thermal one (Hayden #2835). You need to buy the adaptor ($199.95) and OBS fan clutch($189.95), total costs including free shipping $389.90. About the same cost as an OME fan clutch.Was wondering if anyone else has done this "modification?" Thanks, Frank
