Fastener Type for 1966 Charger Hood Trim

[Stowe]

Hello,
I am installing my hood trim on my 66. What style nut is used to mount the hood trim ? All the studs are intact, it appears originally they had cut nuts or some type of speed nut. Any help and or pictures would be helpful. Thanks

should be a machine thread nut.
NOT a self cutting style

The originals are speed nuts.
