Brief Description:  Forward sides install

Positioned the forward fuselage sides on the tail cone. The left side fits really nice, the splice plates are tight all around (good fit). The right side is a disaster. It's a full 3/16" too tall at the splice plates. Meaning with the top splice plate clamped tight, the bottom of the panel hangs 3/16" below the bottom skin of the tail cone. I thought about shimming this (adding shims between the splice plates and the longerons on the cockpit side) and figured this is going to introduce non-squareness in everything else. What to do about the spar box, levelling the thing, it just multiplies into a bunch of compensations that I won't know are right. Not sure if I'll drill the details off the existing skin or what. I vaguely remember the skin itself being maybe 1/16" too high at that point, but I guess the longerons shifted a little as well (the upper one is higher than the skin, the lower one is lower). It remains about 1/8" too high at the front, so shimming would give an inconsistent result, and I don't have the firewall skin for a quick reference of squareness in that direction.
