Specifically the rear seat width and depth. I'm looking at truck seat options near 50" width.
the 2016 interior here is hitting some very nice buttons, but probably not obtainable in a salvage yard yet.
I really like the integrated seatbelts.
2006 and up please.
Interesting. So your planning to use this rear seat as your front seat?
I suspect this will require a lot of substructure for the seat; both cushion and backrest.
For most cars, the rear seats actual structure comes from a combination of floor pan and divider wall between cabin and trunk.
I suspect the seat backs are hard has they tend to fold flat to allow more trunk capacity, the bottom support is something I would have to look at. Mostly exploring options.
Have you considered the front seats from a '00 or newer Buick LeSabre or Park Ave?
If the bench is too wide, they offered buckets too.
