Hot Rods 41 chevy pu

I need to fine rear window trim (really just the inside piece) if anyone could give me a lead where to fine one I'd appreciate it. Thanks

 

Chevs of the 40's comes to mind, but there are many places that sells window trim..... Google it

 

I've tried every site on the net, i was hoping someone might have one for sale or someone might know where I could buy one. As far as I can tell there not being reproduced.
