The lid vent is bolted on. Why would it not be a replacement?
The lid flange is more broad than recent lids. So it's '83- to pre- '97. '83 because of the One Touch sweeps, and by '97 (a least) the lid flange was more straight-down instead of gradual. (Reference: my EI lid is more straight-down instead of gradual.)
[I don't know what year the lid flange became more straight-down instead of gradual. Sometime after '92, based on my O lid.]
