The bottom guide of this metal, louvered door needs a new guide that has a nylon tip, it's worn off completely. I cannot find any labels that have the name of the manufacturer, but they were located in Roseville, Michigan. The doors are very old. I'm the second or third owner. Also I'm somewhat handy but not sure how to replace the guide pin. Does the door need to come off completely? Thank you for any help you can provide.
