A500 Kickdown Band Issue

I'm in the process of rebuilding my A500. I'm having issues with the kickdown band fitting properly around the drum. I normally get parts from WIT, but I ordered the band from O'Reilly's(Part # 767021). The band seems to be smaller. The adjusting screw will not sit in the grove of the band. Has anyone else experienced this issue before? I plan on ordering another band from WIT in the morning, but I wanted to hear other opinions before I have the same issue again after the order.
