Patio screen roller, pacesetter didnt work

I used the photos below and my best guess to order four patio screen rollers, 84-050 Pacesetter, to replace the rollers in my daughter's no-name sliding screen patio door.

The Design is very close, but the width of the roller was too great. Tht is, the part of the roller with the adjusting bolt and the attaching screw hole is too wide to slide into the space between the sheets of aluminum that make up the door. If it is 12 mm wide now, it needs to eight or nine millimetres to successfully slide into place. Here are images of the existing rollers.

Was unable to find any indications of a manufacturer. The wheels of the Pacesetter are the same size as the original wheels. The Pacesetter appears to have the right general dimensions (height and depth), but the width (or thickness?) is too great by about 3 to 4 mm. So, if the Pacesetter measures 12 mm, it needs to be eight or at the most, nine, mm to slide into place. On the original wheelset, the width is such that the outside edges of the holes for the attaching screw and the adjusting bolt come right to the edge of the narrow part of the unit.
Does this help?

Sorry for the delayed response. Took a while to get back to the site of the rollers. Using a standard household tape measure, it appears that the Moss Patio Door Roller is the right one. I'm ordering four from the web site. Thanks.
