I installed the nuts and washers on the wing attach bolts. I didn't notice until the end that the large diameter bolts are slightly long with only 2 washers under the nut and you end up bottoming out. They will need to be removed and a third washer installed, but I will do that tomorrow. A better solution would be to install one washer under the bolt head but it's too late for that because it would be far too difficult to push the tight fitting close tolerance bolts out to accomplish this. I installed safety wire securing the bolt heads at the forward fuel tank attach brackets and installed the AN3 bolts from the control column to the aileron push rod tubes.
