1973 Dart Swinger upper door interior trim panels

I'm looking for nice interior door trim pieces for the front and back of the '73 style dart swingers. As many of you know, the '73 model year changed over from the metal trim to the plastic trim that tends to be fairly brittle, if it's still on the car at all (Mine are shot to hell and essentially unusable).

If this is not an option (as I believe many other people have the same issue), does anybody know if it is possible to graft in the earlier style metal pieces instead of using the brittle plastic for the upper door trim? If not, I may be in the market for some new doors.

Thank you in advance for any ideas you might have.
