Turn Signal Indicators

[JohnXP29]

Need replacement nuts for the hood mounted turn signal indicators (two per signal that mount under the hood) for 1968 Charger.  Does anyone know where these can be found?  One on each side has worked loose and lost.  Thanks

Any hardware store has those nuts.

I believe the original hardware is a 10-24 captive washer nut, some call them free-spinning washer nuts.
