Project 78-5038, Date 4-13-78. The information is listed on the label still - as you can see in the picture, the actual roller has cracked and chipped so the door no longer slides. Need help identifying the correct replacement.

Hi there from SWISCO! Your roller looks pretty close to our 23-042. Just look over the dimensions and let us know if you agree.
