A&S #8138 Door Roller and Height Adjuster

Question

This mechanism clips into the lower door channel.  It is held in place with one visible screw from the outside.  There is a hole in the vertical channel so that a screw driver can be inserted to adjust the door height (and skewed angle).  There is a little rectangular hole on either side of the vertical channel where "out dents" snap into when you insert the mechanism into the lower channel

To be honest, it's hard to picture what you're describing. Sounds like you need an adjustable roller, but I can't really tell which type. Can you send some photos of the roller you're looking to replace, removed from the door?
