OK, Manny, I see what you mean about the chin dome. A file and sandpaper will fix that problem if you want to build the F-4C. The commentary is wrong about one thing. It was not an IRST on the F-4C. Only the F-4A carried the IRST sensor, with the chin dome on the F-4B/C/D housing ECM gear. The reason the F-4D had a different shape was it had a different ECM with a larger processor housed in the dome. Also they were always called chin domes rather than chin pods. Never trust a civilian to get anything right.
