duster deck lid

There are basically 2 different types of trunk lids for Duster/Demon/Dart Sports. Older ones are flat, newer ones have a rib up the middle. The transition time was around '71-'72.

I have one on a '74 Dart Sport parts car. But I don't like shipping sheetmetal and don't plan on racing in NC till next Spring.

I'm in Daytona Beach, FL.
