BOAC, the post mortem summary for bodies recovered from Air India 182 can be found starting on p. 19 of this report:

The mapping of recovered bodies to assigned seats (recognizing that passengers may change seats once airborne) indicates that the further aft a passenger was seated, the higher the percentage of body recovery. No bodies were recovered from the most forward sections of the 747. Also, few of the Air India recovered bodies showed evidence of significant trauma from having seat belts fastened. (That's not likely to be the case of bodies recovered from AF 447.)
A similar mapping of trauma and seat location was done for the victims of TW 800.
