I see there are two different decals for the air cleaners for the 455. Did the Hurst Olds have the decal that just shows "455" or is the correct one have "Rocket 455" for the 4bl HO 455?
Also, where does the other little tag go "keep your call all GM".

 

95% sure 75 still used the Rocket moniker on air cleaner 76 and after no longer used Rocket on the air cleaner.
