Needed lockable storage for road trips.
Decided on the UWS Storage Locker in aluminum diamond plate.
Lining up the box with the front of the step in the tub behind the seats, measured and drilled holes in the channel and mounted it to the tub. Then sat the box on the channels and marked the outline of the channel legs onto the bottom of the box.
Drilled 1/4" holes in the bottom of the box within the marked outlines, then sat the box back on the channels and transferred the holes in the box to the channels.
With the holes in the channels marked, they were removed, 5/16" holes drilled and then tightened 5/16" bolts and nuts to all eight holes.
Used 3/32 6011 rods at 85 amps to tack the nuts to the channel. First time welding in 40 years... I'm happy.
The box is almost a chrome finish.
It just looked too new so decided to scuff it up with fine ScotchBrite.
