it's still in my favorites so I can get the Avi ID and the Authors ID if that helps. I don't know how any of this works. I know you can download private Avatars with SARS but I don't know how to use it or unity.
((im not sure how you'd turn it into an actual .unitypackage if that's what you're trying to do )) but to just get the files you'd go File- Open file- choose your .VRCA- then choose one of the options under Export
