1966 Dart hood lip and quarter panel stainless

I'm having fun chasing down the parts in the restoration of my 66 Dart GT Convertible. I can not believe how the cost has gone up in parts, or it might be the rarity of these old MOPARS. I'm still looking for the stainless on the hood lip and the drivers rear quarter stainless that runs along the top of the quarter panel and curves down to the tail light. If anyone knows I could sure use some expert advice on where to find and, are any of these parts interchangeable with other years.
