same external shape, but that's about all.
except maybe the hydraulics, the main electrical distribution, the engines, 98% of the fuel system, 90% of the conditioning systems, ice protection systems, flying controls, undercarriage, brakes.....etc...

Oh, and no commonality whatsoever with training Air & Ground, maintenance support or Flt crew sim currency. Yeah deffo, completely different.
