For the 4th gen 4runner discontinued skid. I know from the parts dept they come with everything needed to install them, but when purchased second hand they are missing the rivnuts or jacknuts and the install bolt since once installed they are pretty permanent. I finally found a place to get them if anyone needs some let me know, I also know how to make the install tool. Didnt know where to put this except in the FS forum..see example below.
