• Figure 3, the rivet diagram, has a hole with no rivet callout. It's near the bottom of the diagram, roughly in the middle. This hole is only on the bottom side to get the rear baffle oriented correctly. The flange angles are not the same for upper and lower side. Use the same rivet as for the neighbor ones (AN426AD3-3.5). See this FB post for details. See also this VAF post for details. See also this VAF thread for details.
