That is the '71 Demon Sizzler stripe. The Sizzler stripe was carried over to '72, but the difference between the '72 and that particular '71 stripe is the leading edge of the hood does not have the SIZZLER lettering. The stripe portion of the SIZZLER stripe is only the multi line edges on either side. The middle of the stripe is painted flat black.
If you need dimensions I still have the original paint/Sizzler stripe hood for my car.
