Some missing parts needed on a 67 Dart GT Convertible

Nice car.......loks just like mine.I'm sorry I won't be much help,but I know it would be a whole lot easier to put 68 window trim on than finding the original.I'm having a hard time finding that same peice.

Is the 68 window trim too much different than the original one ??
Where we could find this one ??
Thanks for the advice, pal !!!
