Looking for this Artdor sliding door roller

Hi, I need help, I am looking for this sliding door roller. The only marking on it is on the wheel, it says "General Bearing Mineola N.Y.". It mounts on the side of the frame (see picture). Diameter of the wheel is 1 11/16 in, width is approx 17/32 in. Width of the assembly is 7/8 in. The door is from a Northern California house built in 1965, door manufacturer was "Artdor Sliding Glass Patio Doors by BASCD Division of Hecker Mfg. Co.". I need to replace rollers for 2 doors, total 4 rollers. Thanks in advance!

Adding a few pictures.
