Bill, that was the idea to start with but it looked like the Sienna seat would end up too high off the floor.
The Previa seat with the swivel mechanism looks like it was designed specifically for that application and the Sienna seat is nothing like it.
I had previously installed the Previa swivel seat in a Chevrolet Astro using an adapter to fit the bolt pattern. It was a straightforward job and it turned out well. The Sienna is whole different 'kettle of fish'.
