Newbie trying to figure seats

[Gugs68]

Hey guys. I have been here for a cpl years and have never actually needed to post due to the ground that you all have covered over years.
However my search has stalled. My burb two late model buckets and nothing else. I am looking at 2008 full suburban set up. I cannot find if anyone has attempted this with or without success. I am certain it will require fab, but i am most concerned w fitment of width and ride heights for back 2 rows. Any help/feedback is huge. The seats are good enough shape i dont need upholstered, so that is a huge plus. Thx!
Have 1968 burb for reference
