Retrofitting Modern car seats thread

Have any of you tried to take a seat from a modern car, remove the side airbag and the complete seat base/brackets and put the seat back on a base suited for your old car?
Many modern car seats looks good, and are comfortable, but often the seat basees for several reasons are totally unsuited for a small sized hot rod.
I know this would make the seat less adjustable, that's not a big issue for me.
