Can someone tell me what is the correct emissions under-hood decal for a Z registered as a '71 and a manufacture date of 8/70? Is it the silver/white as for the 1970 model (https://www.zzxdatsun.com/catDecals.php) or a gold-tone one with a '71 date mentioned?

There is no emission equipment on this car. It does not have the "new" air cleaner box. Were these applied at manufacturing or in the U.S.? Where did the sticker change?

Any insights are appreciated.
