i came across these pics recently - 2018 seats in a '93. i would LOVE to do this (i also have a 2014 silverado and love the seats - so to be able to drop these in my '89 would be awesome!)
there was a little welding involved, but totally doable!
one thing i'd want to change would be to make the seat belts come out thru the spots on the side of each seat instead of their original location... not sure what all that would involve though.
