Does anyone have any tips for removing them? Trying to swap exhausts on a 97 1500 but the bolts + aluminum clip washers? just spin when trying to remove the nut. I tried to hold the bolt in place with needlenose vise grips and didn't have any luck either. Last resort is cutting them off but figured I'd see if anyone had any tricks before doing that. Anyone?

 

Cut them, and replace them. It's just easier.
