I installed a custom fabricated rear bumper. It came with 6 bolt holes on each side and the underside mount. I mounted to the two OEM bolt holes on each side along with the LOD frame tie in with 2 bolts to the frame. I also used the underside bolts. My intention was to drill 2 additional holes on each side but discovered I cannot get inside the rear member to bolt them in. This bumper will only be on the Jeep until around February. It also won't be used to tow. It's primary function will be a cargo carrier rack to bring beach chairs and a cooler. My biggest worry is that I need to use the D rings and rip it off the Jeep. What do you guys think?
