This is a nothing part, but apparently it is not available anymore. I am looking for the U-nut or J-nut that goes in the hood to attach the hinge. Ford part number 357552-S. I have three, but the forth one is broken. Thanks!
Judging by the number it appears to be a hardware item, check with a mom & pop hardware store or a store like nutty company.
