Dresser drawer parts left and right side

Hello I am looking for these parts, both left and right sides. The side rails are unigrass 6600 series and measure 19 3/4 inches. I also need the back holding bracket both left and right the bracket moves back and forth left to right with markings on the back that say pat's 5.359.723 and 5.349.723. I looked on your web sight that shows this bracket but when I pressed on it, it shows a different bracket do you still carry the bracket I need?
