BMW seats in a 69 Camaro?

[F'in mine]

I posted this up at TC website but figured this might be a better place.
I have an opportunity to buy a nice set of BMW manual leather seats that measure out 37" high x 22" wide x 19" deep for a good price and was wondering if any one has attempted the conversion and or welded some new mounting brackets and could give some insight.
I'm planning to shelve my originals that were re-foamed, still uncomfortable & try something newer that cradles the body better.
Any input appreciated.
