Looking for Replacement Screen Roller

The screen door is about 30 years old. Grooved roller has a 1" diameter and bracket that holds it is about 5/16' wide. It is 2 1/4" from the outer edge of the roller to the end of the mounting tab. It is 1 1/8" from outer edge of bracket under roller to outer edge of plastic adjusting piece. I hope you have a replacement. Thank you. Jeff
