My 71 Olds CS has the cast iron grills with the "Cutlass Supreme" script. I was considering replacing that script with the "Oldsmobile" script as a way to personalize it. The Cutlass Supreme Script has 3 screws that align with mounting holes within the grill. Can anyone confirm either the Oldsmobile script will fit the Cast Iron grill mounting location? Hypothetically even if 2 screws line up it would work. Thanks in advance.
