Jay,
You need to clean out your PM box. I couldn't send you a PM. However, here is what I tried to send:
Remind me tomorrow via email to take some pics of the bumper. I don't use the back up system any longer. I'm thinking that shipping the thing will be quite high just because it's big. So, I'd say cost would be actuall shipping plus $25 for my time to box it up. How's that sound?
