ID Part Help - Heater Contol Assembly

[1967 GT Vert]

Can anyone ID the proper name for this nylon part that the heater cables attach too on the heater control assembly? Where can I get them? The heater core in my 1967 Dart went and in the process of restoring the heater box I found out that this was broken and needs to be replaced. I am also installing a heater core bypass valve as well! Thanks

The Blue felt tip is resting on the part in question.

As far as I know they arent repopped. If they are I would imagine RT specialites would carry them. Good luck on your search, these are a common break.
