Cormac and I spent a good chunk of the day riveting the seats together. This is one of those steps that having two people makes the job go three times as fast. We were able to squeeze almost all the rivets, but the was the rivet squeezer works, I had to sneak up on the head with very low pressure before squeezing. The shop head rivet head needed to be on the plunger end of the squeezer, so you couldn't hold it up to the head.
