Help me locate this part - Window stabilizer guide

Hello... I need to replace the window stabilizer guides on my 1972 Duster. I can only find new ones for E-Bodies but no place seems to carry them for the A-body. Any help is appreciated.

The part is located inside the door. It rests against the window and guides it when cranking it up and down. It has a "fuzzy" material at the end that rides against the glass. The scew that locks it in place is located under the plastic rectangle trim that says "Duster" and attcahes to the interior of the door. I attached a picture of one of mine. As you can see, the end that is supposed to slide on the glass is in bad shape. Any help is appreciated...

Thanks!
