 I had a '92 Buick with a rusted out frame near the back door/trunk area, so the car would flex bouncing down the highway... I ended up putting loops in my brake lines right there so they were free to move with the car. 

You're a man after my own heart Nick - what's a little rusted out frame to worry about. I had a Morris Minor convertible with the same problem - when I had folks in the back seat the doors had to be kept shut because the frame flexed so bad and they had to climb over the side to get in and out......good fun back then!
