I just had an issue with a 2013 fog light bracket that I was able to fix after looking at the official Nissan car parts site. The site breaks things down into components and allows you to order them. I think you'll find the parts aren't that expensive and the installation looks fairly straight forward. You can check the Portland Leaf Owner FB page for my posting to give you a head start.
