Showtime 100 was not the aircraft assigned to either Cunningham or Driscoll at the time of the flight,,,,,,,the pilot's name was CDR Gus Eggert, with ENG IM Fearless on the backseater's canopy rail, in all caps in both places,,,,I'm squinting at the names on a 13" long two page pic in the front of Osprey #30 1972-73 Mig killers book,,,,,,,,,,,,,pilot's flew whatever aircraft they were assigned for any given mission, and Randy wasn't the CAG, I'm just saying that to explain why the names didn't match up (sort of the back story)
let's see,,,,,,2 Sparrows loaded aft, fore empty, 4 Rattlers,,one centerline tank,,,,,,2 TER on the outerwing, with 2 Rockeyes on each,,,,,,in the Slant 2 configuration,,,,,,,,O O X and X O O,,,,,,,easy way to visulaize is "empty on the inside",,,,,,,,I'd dig a little more on the Rockeye loading, just to be sure, if I were you,,,,,,but, for "logic" I'd look at the weight limit for a TER, and the weight of a Rockeye (768 pounds?,,,,,just sprang to mind, you might want to check on that )
I'm not much help with the Trunnion covers in 1/48, they are separate pieces in my Hasegawa 1/72 kits,,,,,,,,,,but, it sure would be tempting to "get one perfect", and pull a latex mold afterward,,,,,,,and be able to make as many as I needed the rest of my 1/48 Phantom career,,,,,,,,as large as those sometimes get molded, making one from sheet stock and filing it all perfectly, etc, would be effort saved in the next few years
