53 chevy trunk repair panel

the rear section of my 53 chevy sedan is rusted out quite badly in that I need to replace it all the way back to the first brace from the back (basically where the trunk latch starts). Does anyone know a place that sells this panel? I saw one on "chevs of the 40s" has anyone used this one? does it have extra sheetmetal to join to the trunk floor or does it just go on top? any help would be greatly appreciated

 

I'm not sure if they have what you need, but the National Chevy Association has a lot of repair panels. (www.nationalchevyassoc.com)
