I installed similar Curt brand brackets on my 04 Dodge by myself. When properly positioned two bolts go through the hat section bed brace and need spacers inside to keep it from collapsing. At first sight with limited access this looks to be impossible. I ended up positioning the spacers at an angle with a loop of mason's twine. Then I used a pointed pry bar to snap the spacers in place. First one took 45 minutes to figure it out, second took 2 minutes to install. I was pretty irritated that they offered no guidance in the instructions to install the spacers. 120 minute install time was closer to 6 hours for me. If I needed it done over again I would find a lift or pay for it.
