The pages respawn randomly, so there is no way to tell you where to get which page. This mission is completely reliant on luck. This mission became a lot harder when it became impossible to pick up pages you already have, so you can't force pages to disappear and respawn.
Complaining about this mission here accomplishes nothing. If you don't like the mission, you can delete it and try for another one in 18 hours, but there is no guarantee you won't get this mission again. If you would like to know which pages exist, you could easily search for them. Here is a link to give you a list of all pages: https://aoitems.com/search/name:phil+and+the+gofles/
If you are still need to know which pages you need to complete the mission:
You need 1174, 1209, 134, 1397, 243, 28, and 747 to complete the mission.
Perhaps it would be easier to remember that 1321 and 1457 are the "bogus" pages.
