This difference will cause the toolbox to bend to the trucks bed. if the "U" bolt does not strike the latch in the proper place, you can adjust it by loosening the nuts on the "U" bolt. {Position the "U" bolt properly & tighten. The "U" bolt may be adjusted inm, out, up or down. (See the slots in welded bracket.)
