Window Frame on a 1966 Barracuda

The front window glass is attached to the regulator by a pin and clip, and a roller and channel. The pin (part of the regulator) and clip, and its mounting hole are shown in the first two photos. The roller and channel are shown in the 3rd photo. Note that the roller for the channel mounted to the window is on the fixed portion of the regulator. The roller on the opposite side of the pin faces the other direction and slides in a channel fixed to the inside of the door. The hidden channel is just behind my finger (on the INSIDE of door) in the last photo.
