To get it out of the way first, some of the holes may not exactly align right away. Because most of the holes are cut before the part is folded, they may be off slightly. This is pretty normal for any kind of formed part like this. Follow the cardinal rule of machine assembly - Start all bolts before tightening any - and you will be fine. I did have to use a bar clamp to align the last bolt, but it didn't take a lot of effort. The end result was a very sturdy step that looks great.I will caution that it does take some effort and a good torque wrench or two. On my 2015 F150, it was a bit of a chore to get the wrenches in to all the tight places they needed to go. A bit of patience, and everything went together.The operation of the step is very simple. It pops up and down with ease. It stays put in either position. Standing on the step feels very solid, and it is wide enough for both of my big feet for good firm footing. I am very happy with the step, and my old knees will thank me.
