The reason I posed the question is that I saw many people having no issues finding their bolts and taking them right off.
I don't have an impact wrench, and don't want to dip into the budget on something that may not work..especially since many of our nuts have been fused, which is why we have used channel locks on the underside. Works like a charm. I do have an angle grinder though, so it looks like after we locate every bolt possible we will be grinding some. It's disappointing how much time it takes. Had to take a week break to visit my mom and we will be back to work Tuesday. Can't wait
Thanks for all the input!
