yup there should be brackets and plastic trim on it. Looks like someone pinched those bits!

Yer if you could post some pics might be useful...He's probably removed them to fit it with a roll bar. It's what I was doing yesterday. Can send post a pic of the bits you need if you want. See if it makes it any easier for you.
There should be two right angled brackets with bolts fitted to them that fit through the two holes on the ends of the bit you have. Then they fit with nuts on the front which are covered by plastic trim to make it lok tidy.
