Looking to replace rollers that have frozen with age and corrosion on aluminum frame (black) Acadia sliding doors from 1962-63.
Pictures attached. Let me know if speaking would be easier.

Hello,
Take a look at our 81-082 roller, which looks close to the part in your photos. Compare the dimensions to your original roller to confirm if the 81-082 could work for you. Thanks for posting!
