Z28 emblems were 3949681 and 3949682. The casting number underneith will say 3949681-LH and 3949682-RH. Service replacements were part number 3957935 and 3957936, and will say 3949681-2 underneith.
In the April, 1977 P&A you could still get both the 3957935 and the 3957936. In the April, 1981 P&A you could only get the 3957935, so they discontinued the 3957936 sometime between these two dates. Sorry I can't narrow it down more.
