I marked the outer 6 of the 712 angle brackets as described by the manual for both wings, then placed the angles aft of the spar, and clamped them down using a C clamp and wood on each. I then drilled the bolt holes to full size. Removed all angles from behind the spar to in font of the spars. and clecod there, to see what they looked like.
Fuel tank 712 angles on the front of the left spar, just to see what they look like.
