So a piece of info came to me this morning that I would like to run by everyone. A knowledgeable person from another site sent back door info that the 69 style cover with the molded in tab was actually a late 68 and 69 issue and that many/most 68s had the 67 style cover and tab. They did say that the 69 style cover showed up on later build 68 year model engines. Can anyone verify that? Does anyone have a 68 with the original timing cover that can support or debunk this information?

Does the 273/318 covers have the same molded in tab in 68-69? If they do then it would suggest that they would not be that uncommon.

Thanks for the all the info, I'm just trying to figure this out best I can.
