Trying to find correct glazing bead

I am trying to find the correct glazing bead to order. Please see the pictures. The one I have is 5/8" on the flattest part. The remaining lip is about 2/8"

I don't know if this helps at all, but the information on the double pane glass itself reads: Dec 7 2005 761855.003 0970 u2c2 LOWE4V 557

Another window next to it (identical size and shape) has the following information on it: Feb 23 2006 797222.3 52

Thank you for your help.
