No offense, Red, but if you are asking this question (& assuming your boyfriend is equally knowledgeable of the process) the best way to go about this is to look up your yellow pages & look for a performance shop specializing in this type of installation. This really isn't a trivial process for someone inexperienced in this type of install. These are supposedly bolt-on kits I believe but still should require some familairity with this kind of upgrade
Actually, if you can get a reference on a good shop in the SLC area from someone knowledgable that would be preferential to picking blind from the yellow pages.
Again, no slight intended - unless you and/or your boyfriend are intimate with this kind of work, not something you really want to tackle.
