Set sweep on both wings. The right wing had quite a bit of forward sweep. I had to cu about 3/16" fromg the "fork" and about 1/8" from the rear spar. The forward sweep is less than 3/8" forward on the right wing to maintain the 5/8" material requirement around the rear spar bolt. Finished reaming the bolt holes on the left wing spar to .374", checked them with a pin gage.
