Had on my 21 JLU for about 6 months. Removed before trading in for a Jeep JT. I do not have the install instructions. If needed they are on Teraflex's website. On of the mounts bolts sits behind the spare tire, my impact was at a slight angle so it slipped on the nut, it is a little beat up but still fine. Teraflex also does not send coated hardware for the bolts holding the jack to the mount. First time it rained they rusted. I wire wheeled those and hit with satin black epoxy paint to solve that issue. Sold as is, no returns.
