The frame looks good, but I am sure it is a little tweeted. I know the rear left frame rail was bent. The previous owner told me he put it on his frame machine and pulled it back where it should be.If that axle tube is bent, I'd make sure the frame is still square. For the the sway bar, I used a set of gate hinge ends to replace the OE inserts. They needed some grinding to fit, but after welding them together they held up. I just gotta clean them up to reuse them again. A set welded in before boxing would help keep the arms stiff with the at the sway bar.
