Rear 9" Drum Problem

Hi all. Asking for some help regarding what could be the problem after changing shoes and all the springs, etc on my driver's side rear 9" brakes ('65 Valiant 170). Everything was put back correctly, but now I can not get the drum back on. It will not fit over the new shoes. I have checked, and know that all the new components are correct (size, etc.). The star adjuster is turned all the way in, and the shoes are in the right position. Could the parking brake have something to do with it (the tension was is released prior to starting work)? Maybe it is sticking? Please help.
