Blackberry z10 stl100-1 housing

HI!
I'm having problems with my z10 housing STL100-1, does not fit well and there are times in which the speaker sounds and sometimes not. I have to press the part where the speaker is to sound. I want to buy the new housing but is authentic blackberry, I need your help on where I can buy it online and that is original in USA.
some pages online where if you can find the authentic?

thanks
