Sliding glass door rollers. No name or numbers found

The door is heavy. Sorry for the poor quality of the photos. The roller is
1-3/16" tall 3/4" wide Just over 6" long to screw attachment points. The adjustment screws are on the side of the roller in the center. In the photos the measurement is taken starting on the 1 inch mark. Subtract 1 inch from the overall number.
There are no names on the door.

The screw holes are probably five and three-quarter inches center to center? I'll pull the door out tomorrow and measure if it's different I'll respond again. Thank you
I'll send better pictures as requested also.
