My plane captain modeler friend said that his G models on the Oriskany and the Midway never had the scoops 70-73. I think I will try and get Kiwi Resins 1/48 G conversion kit, and do the Midway's USAF exchange pilot's bird.
Here is supposedly 146858 at the Museum showing the scoops:

Here is supposedly a 1982 photo of it flying with the scoops:

They were probably retrofitted when they retired the fighters.
