Ok, I guess it is time to explain a few things.
I never set out to be the "Sienna seat guy". In fact, these seats and mounts have taken up so much of my time (my Cummins install time, my pop-top design time, my interior build-out time, etc...) that I've come to the point where I just can't get anything done AND continue to make these. I don't have crew, I don't have a lot of space and, with a full time job, I don't get a lot of opportunity to work in the shop anyways. Sooooooo......
Ujoint has a crew and some manufacturing space/equipment so he and I came to an agreement and we are in the process of transferring the seat mount designs and everything related to them to his operation. As of right now, there are no mounts currently available but there may be a new batch this spring time frame once Chris has the process down. Don't contact me though... Contact Chris and maybe he has a list of interested customers or he can start one.
There is one request I have to make though... be patient, please. If it wasn't for Chris' willingness to take this on, no more of these would be made. I had reached 'peak seat mount' long ago and I was ready to shelve the design. Now I'm in the final stages of tidying up the design files/drawings/bill of materials so Chris can get up and running with no surprises. A comfortable alternative for E-series seating lives on.
That's the status. More on the way, just not from me.
