I don't know what a fish scale even looks like...

Give me a closeup pic of how you have it hooked into the toggle. I would hate to damage it while doing this.

Go back to the first pic; the gauge has a square hook that I hook into the slot/cavity of the toggle knob...The hook is 5/32" brass rod...

Edit: Thor was right about these flat mainsprings...The more you do them, the easier it gets...
