Dart 1963-1966 Wheel well trim

welcome, Always am surprised to see overseas owners of old mopars. I have a soft spot of overseas built Dodges and know that Brazil built Darts.
One thing to suggest is to confirm exactly how your body compares to US built cars so that the reference point of the US reader is clear for interchange. Your photo shows more of a 1967 Dart car, and I have known that South American models often ran for 3 years with a body style, and nameplates were used different than US models. Is your car built in S A ?

Note: 66 Dart front wheelwell trim only fits 66, and rears only 65 and 66 fit.
