Technical Trim I.D. help

So I recently acquired a boat load of exterior trim for 1965- ??? Pontiac full size wagon and or full size 4 door parts. I can I.D. most , but these have me stumped. Seeing the guy that had this stuff was a Pontiac purist, I'll assume these are Pontiac piece's. If you have a guess or know, let me know. Probably going to get rid of the vast majority of the stuff ( 150 piece's or so ) and keep some for a slightly OT wagon project I'm doing. Thanks for any help.

 

For the record this is half of the set which the other piece's are mirror images of the ones in the photo's.

 

Kinda looks like sill plates, and some rocker moldings.

 

Thinking rocker myself, but can't find anything on the net as far as images.

 

Any Pontiac people on the late crew ?

 

they look coachbuilt

 

Possibly Jim, Maybe I have parts from a one off Pontiac prototype !

 

? Bottom of door inside scuff plate.

 

Nope, They are about 3/16th's thick and cast. Some too wide for that some too narrow. The guy that had them passed away and took the answer with him.

 

Did a 52 Studebaker that had some like that.

 

Sounds like rocker or lower door trim pieces. Look up some pics of Bonneville Safaris.

 

Thanks, I think this may well be it, I'll keep looking for different images of 65-67 models.
