Parts interchangeability with 74 Dart Swinger

Hello all!

I'm beginning the restoration phase on a 1974 Dart Swinger 2 door hard top and I'm having a lot of trouble finding some interior parts. Everything I'm looking for seems to stop at the 1972. I'm looking for the A-pillar trim, the door panels, the trim that goes above the door panels (not sure what it's called), the interior door handles and a few other misc interior items. I've checked Year One, Classic Industries, Dante's and Legendary Auto Interiors with no luck on my searches. Are there any other Mopar models that I can interchange parts from? What other years could I use? Will the 1972 trim pieces work on a 74?

Thank you for your time,
Dave
