On my MAR 66 Metuchen Conv't...The convertible top folds down and rests on the flat surfaces of the wheelhouses. Those flat surfaces have a thin pad of some type synthetic batting to prevent rattling. (C5ZB-7632208)
Mine are ratty and I'm redoing them. They WERE white with a green upper surface. Is that the norm? The padding that Mustang parts houses have as the padding for 65 66 convertible quarter trim upholstery is a very close match except for the green upper surface.
I was hoping someone might have a picture of an unrestored car showing this detail, to compare the way mine looked.
