The decklid surely looks from a pre-64 with later registration plate light housing installed. So the T-handle DOES belong to the decklid and correctly so.
Looking at the door posts/slimmer window frames, I am guessing its a post 64 but from this angle, I cant be too sure. IMHO, it can be a "molested" 65!
Having said that, all the molestation that she has received, still can be pretty much reversible to me.
