Replace Glazing Bead on an older Pella Window

I just had a double pane glass replaced due to a large crack. The window I am told is Pella and it's incased in wood. The installer couldn't save the glaze bead because it was brittle and cracked and broke. He wasn't able to match it with what he had in stock but mentioned I might be able to locate it through Swisco. I could not find a model or serial number or other identifying marking on the window. The photos are of the actual piece of the glaze bead that came off and the window without the glaze bead and a small piece that the installer left in place. Do you have this in stock and if so, does it just snap in or do I need to use an adhesive/caulk to glue it in.
