Replacement bead for Hurd wood sash

Looking for vinyl bead for 1980 hurd windows, all wood, glass inserts from the outdoor side. Pics attached. The IGU is 5/8" thick, NOT 3/4". I've replaced 4 pieces of glass in these windows so far so I know how to do this. Old bead has been painted green on the outside. Some new bead is also shown and I used this on the replacement glass for one of the windows I've already done. Outside measurment on the bead I used (and can no longer get) is just a hair over 7/8" on the inside part and 9/16" in the outdoor part that shows and will be painted green. I'm going to need bead for about 40 IGUs. Thanks, Jay
