I'm near Asheville, NC.

It has one strap with it that has a rubber coated hook on the end that I
think goes to hook into the gap between the front door and the body.  You
would need another one of those for the other side.  Not sure how much the
shipping would be on this so it may not even be worth it.  Let me know if
you are interested.
