Flipped the skeleton, laid the skin out, clecoed...all holes lining up!!
Reflipped skeleton, measured for the L's between the ribs. I decided to cut all the L's needed for top, bottom and the other wing as well. I stacked 4 of the L brackets together and went to town cutting four at a time with the thin metal cutting blade on the grinder. Then on to the scotchbrite wheeel to clean them up and deburr the edges. Got the first couple attached with 3/32 clecos.
