Hi Nate,
I asked some people and this is what they said
"As for the convertibles, Ford didn't offer it until 83. In 85 the rear moulding became bolt on and remained that way thru 93. As for interchangeability, you should be able to swap them out without any major issues. I am not aware of any significant differences that would be visible once installed or prohibit you installing a 4e onto an Aero or Aero onto a 4 eye."
