Rangefinder hinge?

[NikTrooper]

I have a servo in my helmet, and used to have the remote on the gauntlet. However, the receiver stopped working and it never worked properly anyway, going down and then halfway up again. So I took out the receiver and just left the servo in. Now the servo mounting has broken and the stalk pops out so figured it's time to find a new solution. Is there a clever way to just be able to move the stalk up and down by hand? Rubber washer?

Stalks are usually held in with a bolt and nut depending on what helmet and ears you have. A tight bolt and nut combo should also allow you to move it by hand when you're gentle.
