I am looking for 2 replacement rollers for our sliding glass door. I'm hoping these pictures are enough to go by. The door is approximately 30 years old. I hope this is all your need.3

Your roller looks close to our 81-011 patio door roller. However, in order for you to confirm it, you would need to remove the part from the door to compare your measurements with ours.
