Joseph,
She looks good.
One suggestion, on the triangular piece, add a plate nut on the top and put the screw for the adel clamp in from the bottom.
The reason is, you are going to have to disconnect the vent lines but leave them in place. Tape off both ends of the lines and the fittings to keep junk out.
You will do a lot of work in that area and the lines have to be moved out of the way to rivet on the top foreskin. The down side is, you can't put the lines in place with the rudder bar and all the rest of the stuff in there, so, as I said, it has to remain in place, just not connected.
The aforementioned plate nut will make installing the adel clamps much easier. This is another place where I used 8-32 cap screws from McMaster-Carr as they are very easy to put in while working on your back.
