The base of the sienna seat is really tall, unlike most seats. Because of this, I made one style of adapters that put the seat at an appropriate height from the floor to work in the Eseries driver/passenger positions. The adapters I have are not made to be used with any other components. They simply bolt to the floor surface.
I've never tried to mount Sienna seats to the adjustable bases and I am not taking on any more Sienna seat mount work so if you want to buy just the seats, I'm happy to sell them without any adapters at all. There is probably a fabricator out there somewhere who can make something work.
Do you make a passenger side swivel for the Scheel-Mann seats that will mount in a 2006 E350?
For Scheel-Mann seats, you can buy adapters that work with either the factory (non-power) base or with the commonly available Eseries swivels (like the ones sold here on the forum or through SMB). The adapters are sold through Scheel-Mann directly.
MG - is there any way to purchase the swivels that you or base-fab used to sell for the siennas? I have a set of 4 Sienna seats and bases that I bought from base-fab, and I'm seriously kicking myself for not going ahead and buying the swivels. Now I need 2 to finish my van. Any help here would be hugely appreciated. Thanks.

Unfortunately, for a number of reasons, I've discontinued development of swivel mechanisms. I haven't tried any of the plate style swivels out myself but many of them are similar in dimensions to seat bases I used to sell.
