The only bad things about these are the washers are not flat on the bottom so they dig/cut into your paint as well as the black bolts will rust. I sold the same things on here last year. To fix both of these problems, I went to fastenal and got the rubber grommets to put under the washers which worked out beautifully. The other thing is the bolts, I started selling the stainless bolts to fix the rusting problem. Not trying to steal your thread but figured I would give you the heads up.
