Today, I fit up the side skins. Initially I had a problem the skins were 1/4" off from the afte fuselage. I went to the old standby, Dan Checkoway's web site. Dan had the exact same problem. He solved it by clecoing the aft seam first, then the rest of the skin. It works for me to. AFter that, I fit up the firewall and the forward, bottom skin. I drilled the side skins. It was too late to drill the firewall. I'll try to get that in the morning.
