I'm getting ready to put my tub back on the frame. Of course, when I took it off, I had to cut off the bolts on the rear body mounts (the ones that mount on the rear bumper). In previouse discussions, it was suggested that I just weld a new nut onto a piece of sheet metal and insert it into the channel.
My question is this. I need to cut an opening in this channel to remove the old bolt (and treat the rust). Where should I cut the openings? Should I:
1 Cut through the outer sheet metal
2 Cut from behind
3 Cut from underneith
I started cutting from the outside (right under the fuel filling opening) but it seemed pretty thick, like there was some sort of reinforcement in that area. Before I went any farther, I thought I better ask the experts.
Any suggestions? I'll try to get a pic at lunch and post it, but nothing right now.
