U Clip Woes

I didn't think it would difficult to find a replacement U Clip but I am pulling my hair out. I have checked 2 auto parts stores and 2 hardware stores and have yet to find them.

The bolts are #10-24 1/2 inch. They are used on the grill to hold it to the body. There is one bracket on each side the top and bottom most bolt has a u clip that mounts to the body. I can't find these clips anywhere. I found them at Fastenal but I have to buy 25 of them for 15 bucks. I just don't need or want to spend the money if I don't need to. Can anyone suggest another place to find them?
