He says the auto AC doesn't work anyway

I'd try and get the tranny+accessories only. That way you avoid any issues with importing vis-à-vis EPA and NHTSA (though comes in outside the 25 year limit).
If he's willing to send over the tranny, flywheel, and driveshaft I'm super interested! That said I might be back in France later this year for 1 year(and will go to Val d'Isère to snowboard in March in any case), and will try and scope out a manual for my TD.
