Re: Van seating options and bolt holes...
Our 2003 E350 XLT 15 pax only has holes for the seat locations for the bench seats it came with. nothing is drilled nor tapped for anything other than as factory delivered.
The seat holes for the first bench seat are wider than two and three. Been a while since I had the four seat bench in place, but seem to remember it is wider than position two and three as well. I drilled an extra set of holes at position three and made backing plates so I could position the four seat bench at location three if I needed to. This gave me 12 pax capability with plenty of storage behind.
