Window glaze replacement

The one that looks like a Z is the vertical glaze piece. The one that is almost flat is the horizonal glaze piece. I can not find any name or numbers on the window. the house was built in 1980. windows are original, I think. Both are about 3/4 overall. The flat surface on each one is about 1/2 inch. the part that goes back to the glass is about 1/4 of an inch. These are on the inside of the window and the windows are aluminum frame. The windows had a metal divided light piece that snapped into the window glaze, that could be removed to wash the windows. Not sure if that helps are not. However I am looking for the vertical and horizonal glaze pieces. Thanks-Clint
