I received the storage boxes as promised. They installed reasonably easily with a couple of required modification and one item I changed due to my own requirements. 1. The brackets which hold the locking mechanism are supposed to bolt directly to the inside of the 2021 F150 bed. The holes in both the brackets were off by 3/4 of an inch. In order to install the bracket I had to put it into a vise and squeeze it so the 4 holes would line up otherwise it could not have been mounted correctly. 2. One of the locking mechanisms itself was slightly bent and again had to be put in a vise and straightened. The supplied screws which are used tp attach the hinge mechanism to the truck body were not something I would ever use. They were cheap and would eventually rust. I replaced them with stainless steel nuts, bolts and washers. The replacement of the hinge fasteners was my choice. but, for me, was the right thing to do.
