I bought a right 04 slk seat rail from Ebay to install on my 07 limited roadster passenger side and started the switch process. Thanks to Red Runner and Lag Dan for all the time and effort put into the instructions and photos . The problem i'm having is there looks to be other equipment on the bottom of my seat, a occupant sensor system with the purple tags is in the way of connecting the new seat rail. I can't attach the screw drive and motor because it won't clear those parts. Is my 2007 not compatiable with slk seat rail ? Thanks for any help Dcskmail
