Early Christmas! I came home to a big Lycoming box in my driveway. Yep, the truck driver just dropped it off when I was not home and no signiture. I got the engine through Vans its a YO-360-A1A. In the meantime I finished the outer support seals and riveted them to the outer sub panels. I then put assembly back in the plane. More fitting and drilling. Notice the upper two rivets on the rib to outer sub panel are flush,
