1957 ranch patio sliding glass roller assembly

Hello there. I'm afraid I could not locate a roller like you show in your photos. Take a look at the roller housings and wheels I've listed on this page; in particular, see the 81-023. Not sure of your exact dimensions of your wheel or housing, but I have used the 81-023 in the past to replace obsolete rollers. Take a look at it along with the related information from the web site. See if this roller or any other rollers we carry can be used as a replacement for the one you need to replace.
