Bucket Seat Frame Ques

[CornDogsCharger]

Yesterday I purchased some parts from a guy here local that had a shop fire.  Luckily, neither of his two Chargers were damaged.  In his storage (where the fire was) he had these two '70 Charger buckets which were in nice shape before the fire.  I got them mostly for the seat tracks.  The seats weren't in the direct fire but the heat from the fire melted everything.  So the frames are still pretty nice.  Anyways, I removed the burnt covers and padding.  The lowers look the same as earlier models.  My question is, are the lower frames the same?  Are the upper frames the same as what was used in the A and E bodies?
