Front bumper problem.

[.steven.]

I own a Toyota Vitz (Second Generation) and I have a slight problem with the front bumper. I recently hit another car but I didn't do any damage as I barely touched the other car's bumper. The front bumper of my car got a bit pushed in but I've managed to pop it back out. The problem is that the bumper is slightly unaligned and I'm pretty sure that I've lost some clips or whatever the bumper is attached with. What can I do to align the bumper like it originally was and how am I supposed to know if I have something missing?

I apologize if this isn't the right section to post this thread to but I'm new to these forums and don't really know which is the right section to post this to yet.
