Pardon me, the pivot points are bolts, not rivets. Here are some pics of the seat disassembled. Keep in mind that this is the passenger'* seat. The descriptions will reference the left (console side) and right (door side) of the seats:
Left side pivot bolt
Left side recline fastener and shock(?):
Front view of headrest sleeves with padding pulled back (hint: turn 90* to release headrests):
Seat cover inside out:
Seat cover right side out:
If you have the same color seats, this one is for sale. I can not use them to replace mine due to the bolsters. Bummer, too. It is in great shape.
