Step 2 on page 29-02 says to overlap the F-01483 forward bottom skins, F-01484 center bottom skin, and F-01454 muffler shroud ramp as shown in figure 1. I want to confirm that I have the right overlap for the muffler shroud ramp, which appears to be shown above the center bottom skin. And, assuming that is correct, would this be a place to proseal so as to prevent any oil seeping into the area of the control column?
