'75 Blazer Cheyenne Door trim restoration need bright metal?

[Gregsmx]

I'm restoring and changing the color of my '75 Blazer.

The door panels are in pretty good shape, so I'm planning on dyeing them to the blue color I'm changing the truck to.

However, I cannot find any parts suppliers that carry the Cheyenne upper woodgrain trim piece for the door. This metal trim has simulated wood grain and a bright metal trim around it with paisly script insert. It's heavily worn on the upper where an arm rests on the open window.

I'm also needing replacement rear bed side panels.

I'd appreciate any leads, or knowledge where to find these items.

Thanks in advance.
