400EX Frame

Hi. This is my first post. The other day i wrecked my quad and broke the frame of my 400ex in a few spots. I need to replace the frame and I was wondering if there were any differences in the frames from year to year. Mine is a 2007. I was just wondering which year frames would work for me. The only damge somehow was the frame and the a-arms on the right side. Any help would be greatly appreciated.
