I cleco'd the right wing tank in the fixture, tapped on rib 101R with a small hammer for a better fit and stored both wing tank assemblies on top of the right wing assembly in my garage.
Reading the directions, I'm supposed to cleco the sealed wing tanks to the wings while the adhesive cures, so I'll need to finish the left wing before acutally sealing the tanks. I'll probably dry fit the rest fuel tank parts to get a sense of what's to come, and then start the left wing assembly.
