Query: Extremely poor installation instructions with inaccurate dimensions

The installation instructions are horrible. There are parts in the kit that are not explained in the instructions, but are required for install, and the illustrations do not make it clear where to put the different spacers. Once installed, the wheel carrier impacted the bolt heads holding the 2nd rail brackets, and though the bracket holes are slotted, there are no instructions stating that you need to fully extend the brackets before tightening the bolts. There is no explanation about installing the door stops, so if you just install the stops at the end of the bar, both doors will slide the full extent of the bar, instead of perhaps stopping one door part way so that the 2nd door can bypass it and close the opening. Making an adjustment after the fact requires significant disassembly. Finally, the number of washers provided is insufficient to prevent the end of the bolt on the inboard most rail from extending through the bracket so far that it impacts the slider for the inboard door. This required adding washers and then finding a suitable paint to match them to the rest of the hardware. The ONLY reason that I gave this a 2-star instead of 1 star is because the actual hardware is solid and well-finished.
