I had to ask because the electronics fit on the carriers changes on a semi-regular basis. While it's a bit later than you were initially looking for,
Navsource has a good image that should show what you are looking for. The ship has an SPQ-9B atop the mast flanked by sat-com dog-dishes. I can't quite tell where they mounted the surface search set, but it's not the mesh-backed one that you have floating above the SPS-48. It's going to be a bar type antenna, likely the SPS-67. And, if I had to guess, it would go forward of the SPN-43 set (the thing that faces aft). I'll get you the updated sat-com set when I get a chance later this evening, but it looks good. The main sets (other than surface search) look good.
There is no "circa". A drawing should show the ship as it appeared at an exact date.
I'm also not a fan of people who draw one of "variants", and don't draw the whole series. The Nimitz needs a drawing of its commissioning date, and then another drawing for the rest of its evolutions.
He could probably get away with not drawing all of the versions as you'd get a lot of overlap between Nimitz on one date and Ike or Vinson on a similar date. This presumes he does all 10 Nimitz 'class' ships.
