Review on TYFYB Lockable Truck Bed Storage Box Tool Box for Tundra 2007-2020 Pickup - Rear Driver & Passenger Side Storage Solution Replacing 02ISC2003LBK, 02ISC2003RBK Pair by Charles You

None of the bolts worked. Take two 1.5" 1/2" bolts, four 1" 1/2" bolts, 12 flat washers, 6 lock washers, 4 1" 1/2" thumb washers, 6 1/2" locknuts Remove the taillights and install the bracket, do not over tighten Remove the screws in the brackets, install the bracket and tighten the screws Tighten the two screws holding the clip that secures the box firmly.Fix the box,latch,tighten the bolts at the rear lantern..Adjust the bolts on the latch plate so that the box closes easily,then tighten.Not bad, after you've installed them, they're easy to remove if you need to use the fifth wheel's electrical connectors.Take extra connectors and keep them.Install some wood or thin insulation on the bottom of the boxes.They're hard plastic and i can see en how they become brittle in cold weather or if you drop a hook inside.
