I just put on the Dee Zee this afternoon and I had the same problem with the nutsert. I like some of these elegant solutions, but I used pliers to hold the body while I ratcheted the nut to cause the body to pop out. The slots in the tailgate were perfect in being my 3rd hand. I popped in the allen wrench, a ratcheting box wrench around the nut and pliers holding the brass body. As soon as it started to pop open, I used a rubber mallet to get it back in the hole and fished it up. Also, you'll need a deep socket or crescent wrench to put the nipple on. I only had short/standard sockets so I had to use a crescent. I got it to exactly 8lbs torque... or as close as I could based on feel... which means I just made it tight. lol This was an easy project as soon as I got the nutsert set. That was a pain. I got it (Dee Zee DZ43200) on amazon for $30.
