Help with Classic Trem arm

[Babow2]

I love my Ruby Slipper Classic 02-23-13N. It is my #1 stage guitar (at least it was back in the bygone days when we played out). But....... (there’s always a but).... the trem arm is so loose it swings wildly and will just fly out of the tremolo bridge from even mild-to-moderate movement of the guitar. Is there a set screw or adjustment to tighten how snugly the trem arm inserts and sits in the tremolo? For example, I have a Wilkinson trem on another guitar. If I dive bomb the Wilkinson trem fully forward (strings slack) there is a small Allen set screw that can adjust how snugly the trem arm sits in the trem cavity. Is there something similar on the Anderson trem? Please tell me I don’t have to resort to electrical tape or some DIY solution!

Thanks in advance for the help, and stay safe!

there should be a set screw in the collar the arm goes into that tightens against the black delrin bushing that the arm sits in.
