I drilled the tail will forward spring attach bracket. I also did the rear attach brackets. As with others after I found the attach points, just shinned a light through the fuselage, and marked them. I also had the same issue as other sportsman builders the forward portion of the brackets fall forward to the attach point. Per the factory this is OK and after drilling the holes fall fine on teh outside of the fuselage. I'll whip up a batch of epoxy to bed the brackets and a second batch for the forward spring attach bracket.
