Anybody know which is the correct roller

[Chargerjase]

My window rollers from my 73 Charger have many flat spots on them and I want to replace them. My originals have been inserted and peined over. I am assuming that this one (pictured) is the correct one, but I have been unable to find it in my parts catalog. Can anybody please confirm that this is correct? Also, if anybody knows where to buy them please let me know? This picture is from http://carpak.com/files2/4_WindowParts2005.pdf


Appreciate your help
