A good shop for a good alignment should be somewhere in the neighborhood of $50 to $75. This means the radio is on a bench with the proper equipment, with a tech who can read the alignment instructions written up by the manufacturer and do it right. It doesn't take long, it is more of a setup that takes time. I know of one tech who does this right but he isn't working right now because of health issues with one of his kids. However, Rabbi and others will know others but don't take it to a place where the words "Peak" and/or "Tune" or "Birdwatts" are used for any reason.
Ok so bonding straps aside. What can I do about my antenna sway? That does also affect reception correct?
I do know that the last time I had the radio to when I put this turn on my Aston if there was anything more, he could do them with the last guy did he mention something about screws and stuff or I don’t know, but he said he did a whole lot more than the last guy did so ♂️ this is who I had put the antenna on and redo my radio and didn’t think at all to mention anything about the swaying of my antenna.

Do what others are doing. Buy a 2 or 3 foot of 1/2 inch PVC pipe at a hardware store. I think it's 1/2 inch, you will need to measure the bottom of your antenna and buy accordingly. Paint it black to match your antenna. Since your antenna is 6 foot long instead of 7 foot, try a 2 foot piece of PVC first. On the bonding video from craigsez that I sent you, fast forward towards the end of the video. He does a sweep of his antenna and truck, and you will see the painted PVC pipe. It's hard to tell unless you're looking for it on the antenna. A long antenna swaying in the wind could effect the the signals, but I would be more concerned about the undue stress that is put on the mirror mount.
