non remote mirror Qs on door panel

Hi y'all,

I am restoring a 67 barracuda. This car came as a base trim level with non remote drivers side view mirror. However there is a hole punched in the inside upper door trim for a remote mirror joystick and cable.

I am sure if you had a non remote mirror there was some sort of plug that went into the hole in the door panel, however i have never seen one as most people redo these with the remote mirrors. Can any of you take a pic of what this part looks like for me?

Thanks
Matt
