I removed my sunroof assembly and there are 4 nuts that hold the assembly to the car frame hood. How do you remove the 4 nuts? They have what looks like a 3/4 moon shaped washer that keep them in place and from going through the hole in the 4 spots where they mount up to the sunroof. Any help would be appreciated. I will post a picture later if you don't quite understand what I am talking about.

Thanks,
