Given that you're building with a full-set of accurate parts, and painting it yellow, you might be the first person to recreate the prop as it appeared on the show. So, I hope you take lots of pictures when it's done!
I'm going to withdraw my last ID part that I mentioned for the upper hull. I've been looking at some of the other photos and the part I thought was correct just doesn't match up with the photos. So disregard my post from August 24th. It's not the correct part. I'm sorry to have mislead you all.
Ok, I have a new part ID that I can confirm for the yellow Ready Room model, as I got the model kit the part comes from. The attached photo shows the part circled in red. Two of these parts are used on both sides of the main hull. They come from either of the two following kits: 1. Macross SDF-1 Cruiser-Fortress 1/5000 scale, or, 2. Revell-Ceji Space Fortress SDF-1 1/5000 scale. The part tree number is 7 and the dimensions are 7/32" x 5/32". They are small but they do show in the attached photo.
Keep in mind if you go looking for these kits, there are updated versions that are in 1/4000 scale and are of the movie version. These will not work if you are building the yellow Ready Room model. The parts have been modified and are too big.
There are no other parts from these kits used on the yellow Ready Room model.
