Glazing beads 3/8" & 5/8"

I am looking for 2 different styles. The first one is shown in the 2 photos on the left. The flat dimension is 5/8".
The second is the 3 photos on the right. The dimension in the far right photo is 3/8". The dimension in the 2nd photo from the right is 9/16". Please note the step down in the middle photo which is on the end of the curved portion of the bead.
