Will the 58-175 work in the original Pella double hung tilt windows? My parents had them installed in their home back in 1978 and most of those seals are missing and some of the exterior seals as well. However, the ones that are left look like the picture of the 58-175. We are moving into their house soon. I haven't tried to take them out to take because I was afraid of breaking one, but I have a photo of one that is still in the window. How do I find out if these are the correct ones? Pella tells me they are obsolete and they can no longer get them for me...
