Need trunk width measurement for 71 Cuda

I am fitting up my new sheet metal on my 71 Barracuda. I took some measurements prior to dis-assembly but would like verification that they are good measurements. I need the full opening width of the trunk.

I have mine mocked up with sheet metal screwsand am getting a 54 15/16 measurement. My original measurements were 54 13/16 at the top and 54 7/8 at the bottom. I am thinking I am in pretty good shape, but would like to see what others have.

Thanks
