I would think that they were packaged wrong Vs they sent the wrong ones. They're sold as a 4 pc set in one package. I had the stickon ones on my crew cab, they were ok, but just not to my liking. I lucked out and came upon a free set of inchannels. They came with no instructions and on my first install I was ready to throw them in the trash, I actually did. Before I took them to the dump I was reading some reviews of them and someone posted some pics of proper installation because the instructions were so vague. Went and rescued them from trash, properly installed and now love the inchannels.
