MI windows kerf bulb seal weatherstripping

Question

I have about 22 windows installed 14 years ago and I find that the bulb seals (at bottom of each window) all warped and brittled. I want to replace at least a few windows immediately. I have taken pictures (attached) and measured the diameter of the bulb ~ 0.25 inch, and the dimension of the kerf (protruding) is about 1.7 inch from top.
Kindly suggest SWISCO part number so I can order the weatherstripping.
Thanks.

From your photos and dimensions, I think you should compare your strip to our 58-182 T-slot foam-filled bulb weatherseal. It's vital to compare dimensions, though, because this may or may not fit your application.
