I'm finishing the last touches on a Great Planes Extra. One of my concerns is that I have a spare part which looks important but the instructions manage to cover the placement of this die cut piece in a totally ambiguous way. Anyone who has built this kit may be able to identify it. Its labeled as part #32 and it says its the hatch cover support although I have already installed the hatch cover with its supports and never had the need for this piece. Note: The piece is asymmetrical. Its wider on the left side and it shortens to the right. I say this because it may seem as a perspective issue with the angle of the photo.
