Technical Stainless trim help, what does it fit

These trim pieces were in some trim I purchased, they don't go to my project, I've looked and researched, but still can't find out what they fit. Anybody know? Thanks

 

got to be rear window side trim from something.

 

Looks early '50s GM-ish but I couldn't find a match. The curved transition into the upper rear window trim is the deal-breaker...

 

I was thinking early 50s Hudson, but nothing looked quite like it when I looked on google.

 

Hudson is as close as any thing I could find. But they didn't match exact.....

 

'54 Hudson Hornet?

 

looks like you got it.

 

Or, a full blown Kustom

 

Thanks, I thought someone would know.
