I got them from a friends shop here in town but I think on the nrg site they got them up.. you need some slight modification to bolt it up with the oem bolts I juss grinded a couple of parts that were hitin on the sliders... its stock ride height from the back I used to have a obx muffler that would hit if I had it lower but cops made me take it off cuz I had custom pipin was all the way straight back no bend except for one little 165 degree out the back where it connected to the muffler..
