Legacy Logic Pro 7 Exs24 Instruments - Blues Harp, Trombone...

I know that this topic has been somewhat exhausted, but I'm still at a loss.

I have lost both by Logic Pro 7 install discs and the computer that it was installed on.

Have installed all of the "legacy instruments" via the Logic Pro X > Sound Library Manager

I even tried installing this package http://audiocontentdownload.apple.com/lp10_ms3_content_2013/MAContent10_Logic9Legacy.pkg (and also found this list of legacy packages: https://gist.github.com/rickychilcott/3222c15663dac7d987a1)

I don't see a "legacy instruments" folder in the Application Support directory:

But I'm still missing some sounds (Blues Harp, Trombone...) for my old tracks.

(Just like this person: https://discussions.apple.com/thread/7579707)

Do I need to purchase a used copy of Logic Pro 7 to get these instruments? Am I doing something wrong?

Thanks a lot.
