You are gonna bring the ski to a shop? That's gonna be expensive. No one in my area really works on those skis and I am leary of shops because it seems today they just want to change parts. Gauges are expensive to repair. So you are embarking along and expensive road if you are paying to have this fixed.
You don't need the gauges but you can buy them off Ebay from from the classifieds. Your trim you can fix in the middle position and still have a great ski. I'm suggesting not jumping into anything. Take your time. Good Luck !
