This is quite an awkward activity especially for those of us with big hands and feet. I peeled back the skin and taped it to give me good access to the insides.
The flush 3-3.5s are on the external surface and go in with no problems. The manufactured heads of the AN470AD4-4s which attach the gussett and root rib I ended up squeezing with the manual squeezer, but on the second elevator, I ended up clinching one and had to drill it out. the replacement went ok.
Then like a good surgeon, you get to close up the skin all around with the pneumatic squeezer.
