The spare one I have is not in good shape the short pin that keeps it straight is there but broken off .it does have the gasket.
I don't believe these hood ornaments ever had a spring in them. Both my spare and original are solid.
The same hood ornament is on the 66 300's. I have one I took off a car this spring It's only so so paid $50
There may be another one in the parts my Dad stripped of a car 30 years ago but those parts are in my brothers shed
out on his acreage.
