I got the side skin curves to a satisfactory match (at least I think so - we'll see if I still feel that way when it comes time to rivet). The next step is to drill the longerons to match the side skins. I started on the right side and clamped everything together to ensure the top of the longeron stayed even with the edge of the skin while drilling. I started drilling from the tail, moving forward and inserting a cleco in every other hole so I could remove the clamps as I went. That's a lot of holes to drill! Can't wait to countersink all of them.
