Complete floor pan 1969

What seam?



The one at the right of this pic. There is a 3" fill panel that goes between the front part and rear step up section on 111" WB cars. Notice this pan doesn't have the rear seat hooks or area under the rear seat on it. Demon/Duster pans are one complete unit including said step up section.

Look at the pic I posted, it has that rear seat section.

AMD list different numbers for a Dart/Scamp and Duster/Demon/Dart Sport.
