I am looking for the nut that holds the hood bumper to the cowl. I have the bumper and the screw, but not the nut that fits into the square hole. Must be some kind of captive nut. I can't seem to find it anywhere in my parts bags, so I must have lost it. I certainly would not have thrown it out.

Is there a supplier that carries these? I have searched with no luck.

 

Some hardware stores offer snap in captured nuts

 

Crystal ball isnt working...Year make and model is always nice to zero in on what your workin on

Yeah...duh! Sorry...1972 Cutlass Supreme.

 

Its probably a pretty standard GM part. Most likely the same that is on my Chevelle. You could try AMK. They have a lot of that type of stuff.

Thanks all. I ended up using a small square of sheetmetal larger than the square hole and installed a rivet nut. Seems to be solid.
