attempted to do the cluster repair... fail. I need some advice.

[asma123]

Hi, so I attempted to do the pixelation repair on my cluster and when attempting to remove the temp needle I slipped and pulled the spring in the stepper motor.
I'm wondering if I replace this spring will it work again or will the whole stepper motor need to be replaced?

IF I were to send the cluster out for repair would I encounter the tampered dot or would it be straight forward and just plug it in? (would the mileage I accumulated in the days that I sent the cluster out, would it update to the mileage it should be or remain at the mileage it was when it was sent out?)
Some advice would be appreciated
