The plans say to use the close tolerance bolts to help locate F704 C&D. It is a tight fit - not sure how I'll get them through everything when the wings are mounted. Drilled out all the holes.
The aft carry through spar gets the F704G spacer. With bolts and a clamp on the F704G I drilled the long #30 holes through the spar and thick spacer. I just eye-balled it for straight while drilling. It came out fine.
These two you need to locate from the drawing dimensions
