I my memory serves me those are not rivets. They are actually long helix spiral threaded nails. You can remove them by getting a sharp instrument under the head of the nail and pry it up just a little bit (32nd of an inch) then grab the head of the nail with a good needle nose with serrations inside the tip and "unscrew" the fastener. The spiral threads are long helix. That means the threads only make about 1 revolution for each 1/2" of shank length. On re-assembly all you have to do is press the fastener back into the hole that it came out of.
