After ten years I finally took notice while cleaning the seats that the pleats in the '65 Formula S upholstery are not sewn, but pre-molded into the cover material. Sometimes I overlook details like that.
Yup, most 1960s Mopars had heat embossed inserts in the seats. One notable exception being the 1967 Barracuda. Some are very complex, like the 1966 Barracuda.
