Bulkhead wire size

Bringing up an old thread since it is kind of what I am asking about. I was wondering if anyone has tried to remove the fusible link connector from out of this connector and not damaging the connector or the plastic plug? As you can see in the pictures, both the fusible link wire & the other 10 gauge power wire feed have what looks like extra rubber/insulation going into the plastic connector.
I am looking to pull them both out of the plastic connector without damaging the wire or the terminal end so I can use the wire in a different plastic connector
Thank You!
