OK, thanks.... im going to remove that lever and that rod under the seat then. Im going to use some low profile 6 way electric bases. After i cut that rod out the bases will fit perfect and then i can remove that handle and fab a face plate to screw on over where that handle was for the control switches.

Nice. Post some pics of what you come up with. What are those bases from? That would be nicer than just back and forth like I’ll have.

They arent vehicle specific , they are low profile bases i found online. I imagine they are supposed to be some kind of universal thing. They are $335 each plus shipping and then you still have to figure out how to adapt them to the floor. https://www.discountvantruck.com/rvvanseatbases/rvvan6waypowerseatbases.htm

Im going to use some brackets similar to these to bolt onto the seat and then bolt the seat to the base, then i will have to make brackets to bolt to the floor. I want the electric base to be up inside the seat a little bit so my brackets wont be exactly the same as these but they give you the idea.

Set at Toy Auto Mart in Rancho Cordova. Want $250 each -- not sure if they'll ship.

Look a little rough around the edges -- but some leather cleaner/polish should clear them up real nice.
Two coffee colored ‘18 still available in south Florida... I’ll hang on to them until someone is in need.

They're a dime a dozen on car-parts.com
Course the chocolate flavored ones are in the newer vehicles so they are kind of a limited supply still.

Yes, but you have to find the Sienna Limited's for sale with pictures, look thru the pictures to see if they have the leather recliners in 2nd row.
If no pictures, then it's calling every wrecking yard to ask them if the 2nd row seats are the recliners, wait for pictures.
Since a majority of the wrecking yards don't post pictures, it's takes some dedication.

Youre seriously asserting that sitting in the comfort of your own home browsing the internet and making a few phone calls is somehow labor intensive and requires some high degree of dedication? Heaven forbid you should strain your eyes or sprain your pinky dialing the phone in an attempt to save a few hundred bucks.

:ROFLMAO: If you only knew.
Takes some dedication to sift for possibilities, yes. Meaning, it's not like you can just go to siennarecliners.com and order up some. Well, not anymore at least.
I should have also commented "I haven't found Sienna recliners being a 'dime a dozen on car-part' to be true in the past 5yrs, but YMMV."
Carry on with the Sienna recliner love, they're fantastic seats for the money...(y)

Ya, you wont find much of anything for a dime of dozen anymore. For those of you that are to lazy to do a little research, heres a set of chocolate flavored sienna seats for you... Dont forget to add in the $335 dollars shipping.....

I picked up my brand new 2020 sienna chocolate flavored seats for a whopping $200 on facebook marketplace. Took one click of the mouse, two instant messages, one text message, and a quarter tank of gas. No phone calls involved.

Dime a dozen on Car-Part.com? I don't think so -- sure they're there -- but most are in the $1000 + range for new pullouts.

Yup -- might get lucky by making some phone calls or looking on marketplace/offerup/etc. It isn't exactly "hard" work -- but it's not like finding a bumper cover for a 2000 Honda Civic.

Excuse my mess, i still have sockets, wires, and other tools laying around because i still have to finish the passenger side. Drivers side installed, still have to mount the 6 way electric switch and change the seat belt clicker but the hard part is finished. Sorry for the crappy picture, i finished up in the middle of the night. Will get better pics when i get the other side installed and get the mess cleaned up.

Did you use off-the-shelf brackets for the "bolt onto the seat" part? I've been eyeing these too for my swivel build -- but most of them seem to short. Thinking about just cutting some out of 2x4 angle but would rather just go with off-the-shelf if there are one's you've determined that work.

No, i ended up manufacturing brackets that slide up inside the bottom of the seat, those are then bolted to the sliders which in turn are bolted to the floor using additional brackets.
But my setup is slightly different than a regular E-350 van. Mine is an RV, an E-350 cutaway, theres a transition edge that sticks up about 1.5" inches behind the seats where the floor transitions into the living area. The brackets i made that go inside the seat are all one piece and of course you have to make sure the slider doesnt interfere with the seat recline mechanism ect.... and of course the seat is offset so that has to be accounted for. It took me a couple days of piddling around with it on and off to decide on a good way to make the seat brackets. I didnt feel confident just bolting a couple chunks of angle under the seats even though im sure that would accomplish the same thing and be just as effective.

I have all the brackets made already but i still have to install the passenger side. I can snap some pics when i assemble it and post them here. I just havent been feeling the greatest for about a week now so i havent got much accomplished.
