Sliding doors - worn parts replacement

Question

It appears we have some Anderson 200 Series Perma-Shield (Maybe?) sliding doors in need of roller replacements. Of the three sets, one is nearly immobile and the other two are nearing similar conditions. We had planned to remove the units from the tracks to replace the rollers soon, but thought it best to have professional eyes confirm our make and model prior to attempting this. These are likely original to the 1980's home.
Based on the attached images, are we close to correctly identifying the doors?
Thanks in advance for your input. We hope you had a great Memorial Day Weekend.

Thank you for reaching out to us! We hope your holiday weekend was restful. We believe you have the Andersen 200 Series sliding patio door that they manufactured starting in 1968. They started using the 81-128 patio door roller in 1982, but we recommend removing the door and taking a look to confirm the roller assembly matches ours.
