Greetings - I need at least seven pairs of windows shoes. I do not have an intact one to attach, only the broken pieces shown in the attached pics. I do know that the patent number on them is 3.055.062 but I am not sure that only one size shoe goes with that patent number. Can I be confident that your part 15-015 is the right one for me? And if for some reason they do not fit, are the parts returnable?
Thanks, Ben
