Trim for a 74 Plymouth Valiant Brougham

I am looking to replace the factory trim that runs along the sides of the car from the the front to the back (both left and right side) on my 74 Plymouth Valiant Brougham. I want to keep my car as original as possible. I have looked at many websites, but can only find trim like mine in black. My trim is brown with a chrome frame around it and has a separate Chrome end cap at both ends. Any leads would be greatly appreciated. Thank You!
