Punto 2003 Facia Adaptor

Hi,
I have just purchased a fiat punto 2003 Dynamic, with the standard cd
player fitted. I have purchased an autoleads punto facia, to fit my
kenwood stereo from my previous punto, but have come across a major
problem! The facia will not fit into the 2003 Dynamic, no matter how
much I move it about, push it, force it in etc. I tried buying another
facia from halfords, but still came across the same problem!

Any help on how to resolve this problem would be much appreciated!
