I was looking at several of the magazines from 1962 and they show a decal on the radiator hold down and the one on the oil fill cap. I know someone makes the one for the oil fill cap but can’t ever find it. Does anyone know what the decal is on the radiator top plate? I assume this is a press car that was shared between all the magazines so maybe it was just on that car?
Eric, the oil cap decal is available from “Rubbertherightway.com” and they sell on eBay (free shipping). Search under 1963 Oldsmobile for it.
The radiator sticker is a little harder, it looks like it says “Important” and it must do with Antifreeze. I found these for 62 Buick. You might have to have one made.
