Well, drat. I just realized that when I match drilled the HS0001 doublers to the spars, 710 & the 714, that the hole spacing isn't symmetrical re top & bottom, and I managed to get them backward. The 5th hole outbd from center is supposed to be in a line with it's neighbors and I've got them offset. Still have good edge distance, but because that area is extremely structural, I'm just going to order new parts and do it right. Can't believe I made such a stupid mistake.
