It's strange how varied the results on this are. I have removed the hinges from the tub before, and there was no seam sealer whatsoever on any of the 8 nuts, and I could tell no one had been there before. Got them out no problem. I did however, break one of the 8 holding the hinges to the frame, and there is nothing to grab. I tried to drill it but didn't have much luck, so I am risking it with only 3 bolts on that side for now.
I concur, I was only able to get to any of this because the entire dash was out. Not even worth trying otherwise.
