66 valiant signet pass side vent window

my glass is clear and in good condition, the lower pivot pin is broken and I am not sure if I can replace that pivot part on my window glass, do you know if that is possible and if it is what is the proses ? If you have any parts to solve my problem let me know. Thanks in advance Roger
Just to clarify, do you want the entire vent frame or just the piece that pivots in the frame and holds the bottom of the vent glass?
I have both.
