I'll grant you that their drawings are a bear to get thru, but once you get the hang of their referencing (which I still can't quite understand) you'll see drawing G08-0003 sheet 1 of nothing references the three plates in question, number 01, 09, and 10. The chart in the upper right sends you to the detail drawings. On drawing G08-0004 sheet 2 of 19 that the Center Base Plate sticks out 24 inches from the centerline of the center wall, and is 46.5 inches wide. The Divider Mid Base Plate is 24 inches wide (sheet 8) and Divider End Base Plate is 30 wide (sheet 9) and sticks out 6 inches the other way from the centerline of the end vertical pipe. They are all 1/4 inch aluminum plate. (Sorry, I had to do this just to see if I could find the info.) And on preview, I see Al snuck in an answer.

Yet, I still can't find how long the center wall might be, or how much clearance there is from its end to the alliance wall. Go figure.
