Looking for replacement parts for Weathercraft vinyl

Question

Our windows say Weathercraft 94, and they all have the same issue. Seems the coil has broken off. None of the Windows stay up, they slam shut.

Please see our 15-140 shoe and Series 150 coil spring. I believe this hardware matches what you have now. If you need the other parts, look at our 15-143, 15-144 and 15-145.
