Technical 40's Pontiac help needed....

I have 2 pair of door stainless trim....they are different lengths...I have one pair at 46 5/8 inches long and the second pair at 44 5/8 inches long....I have had these for over 10-12 years and the yard I got them out of is long gone....can someone tell me what they are off of?....''hint''--- I do have a pair of Silver Streak rear spears....thank you for your help.....stan

 

They have a hole for a door handle like a 1941 pontiac

 

Try '42 or '46 Chev Fleetmaster or Fleetline ... just guessing ....
