Guys: Is it possible to convert a -9 into a -7 with a wing change. I have been told that the -9 and the -7 fuselage are the same and the -7 now uses the -9 tail. I call Vans today to ask the question, the gal from Product Line Questions said she had never been asked the question, and I suspect tech guys are still recovering from the Oshkosh long nights. Dan
