Thankyou everyone for all of the compliments and support, I truly appreciate it. I really was never sure how this would all work out, or if I would even sell my original few sets I made. But With the support and trust of many members, I'm glad that I have been able to hook up many people with Lightbar brackets for their trucks. I enjoy being a part of the community and supplying just another way to make our trailblazers/gmt360's unique!
As for the wind noise/howl/resonance/vibration, it is mainly the lightbar itself, not necessarily the brackets too. The lightbar fins vibrating is definitely the bigger issue, which create that high pitched noise several people have experienced. I had the same issue, and learned through experimentation and research that plastic tubing between the most of the fins is a quick easy way to fix it. As for "wind noise" / "slighter whistle", it's really just the simple fact that there is an object on your roofline that air has to flow over. As I stated in my original post, I tested several positions, and could not stop the wind noise, so I came to terms with the fact that it is just a minor side effect of wanting a lightbar. I've driven in several different model vehicles with lightbars, and they all have the same sort of wind noise. This is all why on my ebay page I include a link to this forum and ask that it be read so that people can read all of your guy's experiences.
I do still make these, and will continue to do so as demand comes. Again, my email is:
msrobertjr@gmail.com I currently have 2 sets available, and I can email anyone who is interested the link, or future links. I apologize to anyone that had to wait a while to purchase a set, I do my best to make these whenever I can, and for whoever asks for a set, but Sometimes it can be a while before I am capable of making a batch. I do my best to respond quickly and answer any questions, and then get brackets made.
