I would not mess with the glued connectors. Just cut them off and solder on new ones.

Odd that he super glued the connectors in first place. I never heard of that before. After you get the new parts in use heat shrink on the connectors and they wont come apart. You can always cut off the heat shrink if you need to and put another one on. Or I think DUBRO makes a clamp cover thing that you can snap around the connectors, you may try that also.
