Hey folks
I am an about-to-become Econoline owner.
Does anybody know if it is possible to add a third row to a 2003 E-150 'Chateau'. This vehicle is standard equipped with 7 seats (driver, passenger, 2 captain chairs, 1 bench). Now, I would like to install another bench in order to have a total of 10 seats.
Are there already any gadget underneath the carpet? How about seat belts - are there some already pre-installed for a third row?

Thanks a lot, I appreciate your help.

 

I have the third row seat, floor brackets, and seat belts in grey cloth from my 07(Portland, OR area). The mounting holes should be there, visible from below. The toughest part will be the seat belts, having to remove interior panels to install them.
