I have a tail from September 07 and it is matched hole. Like DickDe said, the newer spar came about in about 2001, it lists the date in the builders book. The center section comes with the wings, but my 2002 wing kit mated up perfectly with a 2008 QB fuse. I called and asked, and they told me to just toss my old center section, the wings would fit with the new center.
The tail has changed slightly from the early to current, in the elevator counterweight area.
