My home was build in 1973. I am not sure if doors are original with home. I believe they are. I will need 8 of them.

Thank you for posting. I'm afraid we do not have this roller. However, you may be able to use our 23-049 as a replacement. I'm afraid I cannot guarantee it, though, so I recommend that you carefully look over its dimensions and use your best judgement.
