Steering rack fixing

[DRCorsa]

I have fixed my steering rack to the chassis with those aluminum brackets but it seems that the rack has a rather measurable play, it's not rigidly fixed on the rack support. The aluminum brackets are rigidly fixed to the rack support, so the play is between the rack and the ally brackets. What could be the prob? I will try to upload a small video clip to show you what i'm talkin about, but until then any ideas?

Did you put the spacers in the correct place under the correct bracket?

Yes, i've installed them but i remember one of them was too tight. I will check again and let you know.

I found out the plastic spacer of the large ally bracket to be a bit loose.
I may have grind it a bit because as original it was impossible to fit under the bracket.
Options? New spacer?
