I looked at putting platenuts in the forward flange of the 704, but saw on the drawing these are not needed now. They will be installed later with the plate that holds the fueltank selector.
I deburred the 705 bulkhead vertical pieces. And I dimpled them. I even dimpled where the second part is riveted on making this about 0.070 thick. The squeezer had no problem dimpling. I also cleaned out the dimples with a few turn of the debur tool.
