After flipping the septum carefully with the forklift to get to the non-grooved side, the new door for HAM7 +X side got new threads on what it used to be the annulus thru hole. Now, the door is in queue to get cleaned. We used this aLOG as a guide, as well as the following drawing taken from the DCC D1900512. Only IPA alcohol was used to cut the threads.
