Do you have a suitable replacement? The glazing is from windows installed in 1978. I have no further identifying information. It is possible that the brand is Crestline, but I can't confirm that.

I'm not sure if we can locate your exact glazing bead. We do carry the 55-156, from Wenco. Take a look at it and see if you can retro fit it to your sash.
