calling all HP7970 tape owners....

Need input from anyone that has a HP7970 tape drive mounted in a rack. Fortunately, all my 7970's have come with the special mounting bracket. This is not a part of the 7970 itself. It is a long flat metal bar that mounts on the left of the rack. It bolts in from the front, and provides threaded holes on the side further back in the rack. While the right side of the 7970 is bolted into the rack from the front, on the left side - you open the chassis and bolt from inside the chassis on the left wall into the threaded holes provided by this mounting bracket. Given that, it would appear to me that mounting a 7970 WITHOUT that special mounting bracket would not be easily done. I'd like to know if anyone has mounted a 7970 in a rack without said bracket and if so - how did they do it? Since I've always used HP racks and the special 7970 mounting bracket my experience is probably blinded, but I don't see a way to do it without the bracket. Best, J
