Be careful on the anti-seize. I only use it in extreme cases. That stuff is so slippery, you can easily over-tighten a threaded part and strip out the threads. Use regular grease.
There't nothing for the torsion bar adjuster to over-tighten against. Anti-seize shouldn't generally be used for parts that have a critical torque spec, like say, head bolts, unless you have a torque value specifically intended for using anti-seize. But on the adjusters there's no torque value, they shouldn't ever be bottomed out on the threads to be able to torque them at all.
