1968 Dart Hood vents
Only one place repros them and other sell the same part... About $350 pr. Even half the price is still expensive. And the ones you find used are pitted up.
I remember used ones selling for $450 pr. only 7 years ago with very little extremely light pitting. But they still needed to be painted orange, black and argent to look fresh. And the chrome wasn't as shiney as new ones.
Used 1969 inserts are cheaper.
