Need help with a small part for a '65

[48Super]

While in the process of cleaning and detailing underneath my '65, I discovered I'm missing the hardware that fastens the outside end of the bumper to the side of the fender. Specifically, I need one of the metal spacers part #1367145 shown in the attached bumper assembly illustration. If you have one of these parts in your junk box that you can spare, please let me know. I believe the same piece is used on all 63-65 Rivieras. Thanks for your help.
