Project "Chihuahua" '65 Formula S Restoration "Estilo Mexicano"
The lock washers that "secure" the hood hinges on the non-threaded pins are loose and cannot be trusted to be doing anything. As long as the hood is attached, I don't see that being a problem. The factory ones probably fell off frequently. I don't know if they can be snugged up somehow once they are put on.
Edit: Forum contributor MOPAR4Me in post #115 pointed out the fact these lock washers are called "push nuts" and the one shown in the photo is reversed. The push nuts should not really be re-used in the first place because they lose tension after removal, and worse yet, if they are installed backwards.
