What is the favored technique for aligning a wing into a full fuselage? Profile planes are simple, straight leading edges again simple. This one has a tapered leading edge straight trailing edge. J.D. Falcon.

What has worked for me is to mark a true centerline on the fuselage using pins and thread.  To get the horizontal alignment I measure points on the wing equal distances from the center then measure the pin to tail and pin to nose distances until they are equal.

Ken's method works for me.  It's just basic geometry.
