Searching for 65-73b in black

Hello, unable to send picture but am looking for black vinyl glazing bead for mid-70's Mayfair windows. Believe the correct bead is Croft 65-73B which you don't seem to have. Appears to be same size and profile as Croft 55-151 that you do carry but black instead of white in color. Bead is 7/16" wide and roughly 1/4" high. I use term roughly 1/4" high because I am measuring an old piece that no longer flexes. Suspect original height may have been slightly higher like maybe 3/8" rather than 1/4". I am not replacing glazing beads on all of my windows, so it has to be black or at least bronze in color. Thank you, Dwain
