Classic Industries side trim issue

[vet57air]

I have done several 64-66 C10 pickups for people. I used Classic industries trim. Last year I had to replace some door trim on these trucks due to day to day damage. I waited for months for them to be available with no luck. I bought a complete set to get the upper door trims (cx1689) to help out customers. I ordered 3 of the door trims 6 months ago and still waiting. Classic says they have no idea when the will get some. I bought another brand but they look different. Anyone know where they source from or where to get?
