I am trying to find out who the running board I have is made by so that I can see if there are replacement endcaps that I can buy.

Thanks

 

This is an OEM running board that is not standard. The original dealer had to look it up from invoice. The part # is 4L3Z16A455BA, just in case someone else breaks the end cap. This is the driver front or passenger back.
