1998 Chevy Rear Brake Lines

I have a hole in a live at the back of the truck. Already disconnected the line by the axle, removed 2 clips holding line in place going towards front of truck, and have found a coupler to disconnect and replace. The problem is the coupler is wedged between the frame, the gas tank, and the bed. How should I approach this? Removing the bed seems to be the easiest solution. Any other ideas? Never had to do that before. Looks like 4 bolts to remove from under the truck, and disconnect tail light assemble. Am I missing anything?
