Finshed up the right flap. I pulled the blind rivets. Read about a trick on EAA web site. Grind a piece of metal to an angle. Then when pulling a blind rivet where you can easily access the shaft, you bend the shaft and use the metal to brace the rivet puller. Worked pretty well.
Unfortunately the rivet puller pretty much gave up the ghost pulling these rivets. Disassembled it and cleaned it but it's pretty much shot. Pretty annoying.
So, I could buy another rivet gun or get a pneumatic puller. Pneumatic one is only $40 verus $20 for a hand puller. Easy choice.
