I looked up your seat and it is a bottom mount unit. they appear to have a universal adaptor so you should be able to mount direct to the floor or to your oem seat sliders. not sure what you could mount your seatbelt receptacle on, however - probably have to fabricate a bracket of some sort (can't recall if the oem mounting boss is part of the seat or the slider assembly ...). in all honesty, the mounting hardware they sell (and the seat) look very cheap - do a gut check and make sure you want to trust your personal safety to something that has not been made to any sort of standard for quality or safety (ie, fia, sfi, etc.).
