Josh, I'd recommend getting the main jigging points from Kitfox - i.e. wing pickup points, MLG pickups, tip of the vertical fin etc. You can then do a mensuration check to see if anything is twisted or not aligned. From reading the fb thread of the guy selling, I understand there's a bend tube above the cockpit - may be a sign of some twist or racking. Hate for you to do a lot of strip down and reconstruct and find you have a twist or other alignment issue that causes some balanced flight issues........ Just my thoughts.
