can any of you tell me what this valve cover filler cap came on from the factory? I am posting 2 pictures of it. I know yall yb members are really knowledgeable and can tell me what it fits. I found two of these in my shop and I have had so many engines over the years that I don't remember what it fits. lol.

Looks like a hydraulic oil tank cap to me.

thanks for the reply, but I know that they fit a 427 ford valve cover, because I ran them back in the 60's. I was just wondering what year model they came on, if it was 1967 or what. I've heard that the 1967 caps are very rare and costly, that they only made them one year. I hope this is them. lol. I think they called them the "cookie cutters" if this is them. information please!!!

could be aftermarket chrome value covers late 60s
