I found the SNX-03-04 form channel and measured and cut the lengths of each channel section that will make the aft fuselage vertical supports. However, after making the second cut I realized that I cut one of the -02 supports 1" too short. Unfortunately I will now either have to order an extra SNX-03-04 section or order some .026 T6 and scratch build it. I'll see what the cost difference is and may just order a sheet of .026 to keep on hand. Laying out the hold patterns for the end of each channel section is quite tedious and time consuming.
