Need help adjusting elements for all resolutions

I'm making a 2D for tablets, and i need to support all kinds of resolutions. I've mostly done almost everything using UI, and it worked great.

but now i've got a problem, with some elements that most be in the "World Space" (since i use flash animation with GAF converter).

so this what happens: in the top part, i work with my native resolution of 2048x1200 in the bottom picture, when i change to 2024x1536, the screen is smaller, and you can't see the whole camera view, so it gets cut off.

This was a non-issue with UI, because of the anchor system, but i'm clueless how can I do something similar with sprites that are not on the UI
