Apologies in advance - I'm a newbie and not sure where to post this.

I'm in need of a new bumper for my Mondeo - in searching around, I seem to be seeing similar-looking bumpers to mine. I'm seeing plenty that look the same basic shape but with different grilles to mine.
This is a typical newbie stupid question, but can I buy any bumper for a Mk3 and will it fit?
I have a Mistral LX registered in March 2004

Thanks in advance.
