Good find.
(I read the ramblings below to myself and realize it is extremely anal retentive, but I just can't help myself, sorry.)
Yup, Wards is right. What you show as Eckerd is too large. You can see three vents(or something on the roof), two close together that probably are right over Eckerd. There was a video store, facing Villa Maria(that went out of biz a few years after Hasting's opened) and a Kids Cuts type place(inside, facing the entry hall) between Eckerd and the main mall entrance hall. To the west of Eckerd I remember one tenent as being a jewelery store(that was one of the first things to close as I recall), one a sporting goods store, and finally a pet store before a smaller "mall" entrance.
The modern Hastings has the same footprint, aside from about 100 linear feet added to the east, and comes pretty close to touching the old Wards service area.
It is hard to tell from the image if the hallway I mentioned was kept and remodeled for Gold's or torn down and a new section built. I don't think that part was ever knocked down, but I may be wrong. Could you find a current image to see? The hall I am talking about follows the east blue line of what you have marked Eckerd south until it hits Walmart, missing the east line you have for Gold's by 20 feet or so.
I was too picky about your description of Gold's. A sane person could clearly understand that the old location was beside the old Walmart. I took you more literally and thought you meant RIGHT beside, which, the new location actually is.
You can see Manor East 3 on the image as the browner portion of the roof north of Walmart.
(By the way, north, east, south and west are relative. In my descriptions, assume the front of the mall faces north, which it doesn't because of the quirky layout of most of our town. It looks like your satellite image is aligned true north-south.)
I haven't been to a Theatre Company production since the new Gold's opened. They performed in the old large theater when I went, but it looks like Gold's might have taken over that space. For those that have been to recent shows, and are old enough to remember Manor East Three, which area do they perform in now?
