1937 C14 Chrysler Imperial parts needed

Hello,

I am restoring a 1937 Imperial C14 (coupe w/ rumble seat). Almost finished but I'm having a tough time finding the running board replacement pieces. The base boards on the body are in great shape and has all the holes for the boards. Just cannot find the correct size/shape to fit this car. I've been sent ones that do not fit...maybe fits an Airflow or other model.

Also, looking for the Imperial hubcaps. I've got the originals but has some minor spots and dings. Would like good ones in shape to re-chrome.

Thank you for your help and advice!!
