After reading some reviews I was concerned about the quality of this product. I just installed it on my 2017 Silverado HD2500. The installation took about 30 minutes, everything fitted perfectly. Concerned it will be held by glue consistent with previous reviews. Mine came with four screws. Very sure. Looks great. My only complaint would be that it's a bit flimsy and flimsy, but that helps with installation. In general very satisfied.
