Andrew I got my horns but I can't figure out how to get the grill off.

I have the four main bolts off but how do I get the rest off without breaking it?

edit/update: OK got the horns in, it was extra easy. I'm a little underwelmed. I thought it would sound like the horn in my Porsche but it is definitely kind of a "small" car horn. Its loud but it doesn't have presence.

Still better than the old horn though.
