To the best of my ability to measure while the window shoe is in place, it looks like I need the 15-046 pivot shoe. But the color of the existing shoe is blue where it accepts the window tongue (i.e 15-015). The steel piece on top looks more like the 15-046 than the 15-015. My measurement for width is not giving me confidence between 17/32 and 1/2. The other dimensions between 15-046 and 15-015 are the same.
Any advice?? Thanks
