I'll go with non-original cigarette lighter. Looks like a metal knob designed to pull, and I once owned a T-bird with lighters like that for the back seat. Certainly that's the same spot where the manual washer pump was frequently installed (on cars so equipped), but they had a straight shaft with a black plastic knob. What I see in the photo is not straight.
Not sure about the rear fender, but my guess is that it's just somewhat mangled. The damage at the lower edge looks like mangled metal instead of Bondo, to me.
Several other DPO-isms visible, like the wrong rear view mirror (given the toilet seats on the trunk lid) and the paint on the instrument panel & glove box lid. Seems like the trim around the "vent pull" knob is missing, possibly so is the knob. Wrong temp gauge, others look strange but might be OK. Extra "lift the dot" stud on the body, one missing on the door.
Door handle looks wrong to me too, like maybe a TR4 handle. The door handles also don't match the toilet seats on the trunk, so maybe it's the trunk that is wrong. Unless perhaps this car was once fitted with the ultra-rare GT option and then converted back to a ragtop ... Nah, I don't believe that either.
