It looks like it won't fit but it does. Take out all clecos in the area and spread the parts a little. Just try to get one end of the shim in and slide it up to the forward end and then push the rest of it down into the gap. The hardest part is getting the holes lined up with the other two parts. The top and back edges of the shim should be flush with adjacent parts.
Wings, empennage, fuselage and finish slow builds completed. Avionics Installed.
FWF in progress (temporarily on hold after unexpectedly having to move from T51 to KDWH)
