We need to fix a sliding screen door upper track and the cranks on living room windows

Thanks for you help, I am trying to replace the upper track of a sliding screen door on our 6 ft, patio sliding door. The track is broken so the screen door will not stay in place. The track is 3/4, there is no serial numbers other than the glass information Along with trying to fix two cranks that open the living room windows - those have imprinting on them that say "Entry Guard - truth" #20810. Any help would be greatly appreciated.
