These rollers install on the end of the window regulator arms and slide into the window channels. If these parts are missing or cracked, window operation can be difficult or impossible. Replacing these when you have your doors apart will make sure you have perfecly functioning windows. Danchuk # 11287 will work on any 1955-1957 classic Chevy that uses a 5/16" rivet. Three required per window; 12 per car. Made in the USA.
Note: There were two different sized rivets that Chevy used to mount these rollers, 5/16" and 1/4". Make sure you are getting the correct size for your classic or the rollers will not work properly.
