General Upgrade Items for buildings

[Old Eagle2]

Do upgrade items remain in the gifts to send area after attaining the upgrade (Example: Smart Glass for Terminal level 8)?

After upgrading you move on the next item (you loose smartglass but gain another item in accordance with the relevant upgrade e.g. water dispenser).

That answers my question. ie I can only get items from neighbors who have the same level as I'm trying to upgrade from.

Correct.
