The next step is extremely critical. I wanted to make sure I understand where the two outside attach bolts go. The two bolts will have to go through the longerons. I had to make sure there is adaquate distance from the edges as well as the vertical member. The available distance on the longeron is 3/4" but the vertical member is 1/8" thick. Therefore the available distance is 5/8". I wanted to put the bolt in the middle of this distance (5/16" from the edges). I have to transfer this position to the angle brackets. After trying a number of tricks to accomplish this I decided to transfer the position of the longerons on the upper mounting surface. Wil do this tomorrow morning with a clearer mind.
