Which glazing bead for NuAir window

A home owner from Oklahoma says:
These are NuAir windows. The label says 900 series. Hail damage to glazing. I am not sure if 55-029 is the one that I need.

Each side is 1/2 inch. The notch seems to be a little different than the 55-029.

We do believe that our 55-029 is the closest match we have for you. However the notch is a little different. We have a sample program where you may be able to order a sample of this glazing bead to try out prior to purchasing this if you like.
