Brazilian Dodge Dart 76 (similar to 69 usa)

Are those grilles and headlight bezels hard to get?

grill is easy to find. But usually requires some restoration. About 200$

Hood trims I think is just the same US model. don't know the price.

J like trims are hard to find. But a friend reproduced them using solid aluminum cast.
(about 100$ pair)

headlight bezel is not rare. About 100$.

As you noted, parts in Brazil are expensive :(
