Where do front brackets go?

My tumble dryer indesit Idv 755 was making a awful racket so I took it apart and figured out it was the guide bracket ( of 3)from the bottom of the front of the drum. Anyway to make a long story short there are 2 metal brackets on the front ( under the plastic bottom front cover) I can't figure out how they go back on, I've tried so many ways to turn it, back to front and I just can't logically find the answer. Any help would b appreciated
