Sorry, I don't have a decent photo editor on this computer, so I can't help out with a picture. You should be able to be able to post photos that you have in your gallery by copying the BBCode section from the photo details and pasting it into the message text.
BTW- the wheels on the Grand Cherokee have a 5x5" bolt pattern while the Nitro uses a 5x4.5" bolt pattern, so they won't fit.
