The shape of the aft part of the engine nacelle of the excellent 1/48th Zoukei-Mura F-4J Phantom has been questioned. For what it's worth to the discussion, this is a depiction of the cross sections from pretty good drawings produced by McAir. Note that it depicts the Blue Angels F-4J, almost all of which had the F-4B J79-8 engines installed. However, the nacelle shape of the F-4B/N/J/S forward of FS 493, i.e. the unpainted "finger plate" surrounding the afterburner nozzle was the same.
