68 Barracuda Hood Safety Latch Spring
You could use any Mopar latch spring from any donor latch of that era. Problem is the rivet/pin.
You might be able to reuse your old rivet/pin if you remove it by grinding the edge flush with the latch. Then punching it out. Then drill a shallow hole in the grounded off end. Reinstall and stake out ground end with hole with center punch. **Caution. That is just an idea, I have never done that personally.
OR, just put a bolt and nylon lock nut on it.
