Thanks for posting. I am afraid we don't carry this exact kerf seal, but see the 58-053 or 58-055. Compare with your old kerf seal and see if you think either could work for you.

I also have 90s NORCO windows in our home and the weather stripping is falling off/out. I am in need of a good solution. Casement windows in this home are wood with a white exterior; if that helps.

Hey there. Does the end profile of your old seal look at all like what the original poster showed in their photos? If so, the 58-053 or 58-055 might work as substitutes, but we cannot be certain. Take a look and see what you think.
