Left Control Screws - Tightening

So, I had two vehicles at the Harley dealer (where I just bought my bike 2 weeks ago) and asked them if they could stash my motorcycle inside overnight until I could get a ride back to pick it up. They were more than happy to do so. However, when I picked it up and rode away, I noticed that the mirror was wiggling a bit. Further down the road, I realized that the entire left control assembly was lose. I know it wasn't loose when I dropped it off the day before but whatever, that's another story for conspiracy theorists.

Anyway, I was able to finger tighten the screws enough to get it home. I saw another post on this forum about someone who had the same problem and it continued until he torqued it with loctite. Should I go ahead and loctite and torque it now? If so, does anyone know the torque specs for those two screws? I'm probably overthinking this and should just tighten them without worrying...but i just thought i'd ask.

Also, on another subject, the turn signal relocation kit is something that I can do on my own, correct? I just purchased a touring windshield with the kit and it should be here in a few days. Thanks guys.
