Finished the rear seatback! Shot and bucked the rest of the rivets without issue. Used an offest rivet set on two of the rivets. I taped the rivet set to the gun to keep the set from rotating. Then used the squeezer to set the rivets attaching the hinge.
Used offset to drive 2 rivets
Rear seat back finished
