Thanks to help of my dad I finally got cabin cover to fit, however there was a huge gap present. At first it didn't seem bad, but then it woudl not clamp close. I couldn't figure it out until I posted on Matronics. Turns out the quickbuilders put universal rivets in door opening and not flush head rivets that I had to overcome that to get cabin to fit. I have sent email to Van's to see how to proceed. I wish I woud have just build fuselage myself after all the problems I have had with it.
