I think this is what I need. Ours are so old and broke it is hard to see and measure. The one with the red ruler shows the entire width of the plastic and the other one is just the part that slides in the groove on the window.

Thanks for writing in. Depending on the measurements of your part should determine whether our 58-182 or 58-171 bulb weatherseal would work. Review both parts mentioned carefully and let us know if either of these would work for you.
