Not from 682 drums, but from Jobeky a few years ago I had the same issue. I had to get a longer tension rod from my spares to put on side on REALLY tight, then put one of the 2box rods on either side of it, replace the longer one with a 2box one and do the same the other side, whiles kneeling on it with my full body weight. Yeah it was a task but that's how I did it. If not for the longer tension rod, I'd probably not have gotten it on.
