There are official dimensional drawings available for this device. If you go to the NI SCB-68 product page and select Resources » Dimension Drawings you'll be directed to this page: Dimensional Drawing for SCB-68.
Hope this helps!

If you look at this article: http://digital.ni.com/public.nsf/allkb/F011AD8B0F4BD35086257050006CBB70 it gives links to all the different SCB 68 reference labels and pinouts. I hope this helps!
