What edge distances are you using for 3/32" dimpled holes (AN426 Rivets)?
If I reference the MIL-R-47196A spec on Vans Website it shows Flush Rivets, Dimpled Holes as the "A" & "B" dimension (0.156").

However if you look at the original 1977 MIL-R-47196A spec it shows the same scenario as the "C" & "D" dimension (0.219")

Is this a discrepancy, or is the Edge margin reduced?
