I don't know the make of the windows, the shoe glide measures 5/8" x 1 1/4" x 2"
window has consecutive numbers one is GRD-M-137521-E
I looked at your inventory and found nothing that looks like it will fit the window swivel arm......

You're right, that pivot shoe has a bit of a peculiar style. The hole in that center cam is not a standard shape. Before I suggest anything, would you please show me a picture of the pivot bar that goes in that hole? I can't guarantee that we can find you anything but I will do my best. |
I found those pics ,,, see if this helps...... by the numbers on the window , can you tell me the make ?

Thank you! That is a huge help. What you have here looks like our 26-218 pivot bar. Now, this usually works in conjunction with the 15-187 pivot shoe. However the design of this shoe differs from yours slightly and I'm not 100% sure if it will work in your case. I guess it would come down to size. I can already confirm that the 15-187 will connect to your spiral balance in the same way, so we have that covered. I can also tell you that it will work with your existing pivot bar, assuming yours is a match for the 26-218 like I think. So at this stage the only question is whether or not it will fit in the track. I'm optimistic that it can. Ours has the same 5/8" depth and 1-1/4" width as your original. It's taller at 2-1/8", but height rarely comes into play for pivot shoes so I think we can safely ignore that. Right now I think this is a promising option. Granted, the design is still very different from your original, so this isn't a guarantee. But I do feel optimistic that it will be compatible with all your old hardware and fit in the track, to boot. That's really all a pivot shoe needs to do. Look it over and see what you think!
