Restoration Specialites has the clips for the trim across the nose of the hood, as well as lots of other stuff. There are a few sizes of that same clip design so have yours handy.to measure. They are the exact same clip.
You can download their catalog here: restorationspecialities.com.
There’s another one in New York I think that is a “manufacturer”of a lot of these old clips but the name escapes me right now, I’ll see if I can dig it up.
I know we got new clips for that rear trim but I need to depend on someone else memory for those. Some here certainly has sourced them.
Google classic car trim clips and several suppliers come up. Have a clip handy and call around.
