Then you have to make sure the seats are centered in the truck properly so if the air bag deploys in an accident it doesnt knock your head threw the side window or something odd.
You missed probably the most important point. Seatbelt clasp is identical between the two, but the Ford clasp has a tensioner in it set to activate on airbag deploy where as the sienna doesnít. So there is some modification that needs to be made to the sienna seat to make the Ford clasp fit. But yes, you can make the sienna fit in the perfect location, while ďjustĒ missing the B pillar.

Thanks for the reply. My van already has a power driver base. Plan is to mount a swivel and create my own brackets for the sienna seats. Iíll track the process and see if I can make something work.

2004.5 Ford E350, Clydesdale 4x4 Conversion, head studs, egr delete, SCT tuner/monitor, much more to come..
