Official DEC card mechanical specs

I've been more seriously contemplating my QBUS multi-purpose card idea now that one of my other major projects is nearly done. I've been unable to find any official or even quasi-official mechanical specs for DEC cards (QBUS, UNIBUS, etc). I'm obviously looking in the wrong places, since there's a wide degree of uniformity; I'm looking for things like board outlines, edge bevels, component clearances and the like. The electrical specs are in quite a few places, so I'm not worried about that. Interestingly enough, my Douglas CAD software for my old Mac has DEC card outline templates pre-stored. However, I'm not even entirely sure Douglas makes PCBs anymore, and I imagine they can't beat my preferred board house on price (I'd love to be wrong). - Dave
