OEM canvas configurations i have seen come in:
1 window...no side windows ( van style )
3 window...1 in back, 1 on either side
5 window...1 in back, 2 on either side
7 window...3 windows in back (2 smaller 1/4 windows and 1 center window), 2 on either side (called the 'seven window' soft top some people call it the safari top...but have yet to see one on a safari rig

)
and then the Ambi door soft tops
then you have zipper windows and/or twist lock windows
I will post some pics up soon...kinda forgot to add to this thread
