you could always pick up two stover/bowma-grip nuts, and pardon the description but every mechanic has a different word for them, they're a locking nut, but they have a very slight triangular shape to them to they really bite and lock in place. I know from experience that with a dab of loctite, they're not coming off without someone in your neighborhood hearing the guy swearing about them and kicking the tires lol. I used two on mine, so they're as safe as they can get, unless like the other guys said, you buy a good alarm

 

Best option is "bathing" the bolts' threads on red loctite. But then you also forget about removing them yourself. Red loctite only lets go with heat.

Of course, there's always the risk of the methheads breaking everything in the stealing attempt.

Good luck!

 

yea i think I'm just gonna risk it, i don't wanna get in the situation where if i wanna adjust then i can't do it. but those options actually sound tempting. thanks!
