Leg shield tool box.

Evening all.
I'm going to fit a leg shield tool box to my GP. I have searched the forum but I am still none the wiser. If I put the box where people say the brackets are miles away from the holes. There are no instructions with it so I don't know what to do with the loose brackets, bolts and pop rivets. Pictures of work in progress would be nice. Any tips at all really.
Cheers
