Duster and Dart parts

I have a 70' Dart grill with some broken mounting tabs, a front bumper that needs re-chroming and the trim across the hood and around the head lights, I'm not sure how to price them, I want to be fair but still make a buck or two!

Any seat belts for the Dart. And what’s your buddy want for the Duster panels ? Also bumperettes for the Dart ft and rear?
