I'm no expert, but I've owned over 10 cutlass/442 over the years. The molding on your car was an option on 70-71 supremes. I also had a 71 supreme and it did have the rocker molding , the same one used on the cutlass salon( fastback) model. My 71 didn't have the script on the trunk or any c/s emblems, so maybe it wasn't a supreme and just the notch back style cutlass. We are probably both correct in both ways. The hood stats you stated are correct, as the 70-71 supreme and Vista used a different hood from the 442 and salon.
