HP 2895 (paper tape punch, facit 4070) assistance sought

This weekend I actually got around to building my final HP2000/Access system. Today was spent completely disassembling the dual bay rack, cleaning, touchup painting, and reassembling. I finally have the "right" racks that HP2000 was usually sold in, so everything matches the HP2000 site preparation and installation guide. I'm taking large amount of pictures of the restoration, and at some point I'll get them up on the web along with descriptions. I'm doing it with 2100's again, but I'm trying to come up with a way to use E series machines. One thing I was looking at... HP has a 2895 paper tape punch, which is actually a facit 4070 bit with a totally custom drawer/slide thing. I can not figure out how this thing is supposed to contact/mount with the rails in the rack to save my life. Does anyone have the 2895 rackmounted, who could offer a few key clues as to how it's mounted in their rack? The installation guide doesn't address rackmounting. Thanks for any help! Jay West
