Pam, iffen you were close by, ..... I'd give you a pane of glass you could cut and replace those replaced ones with.
I have several of them, I think, which I saved for such things when I helped a friend replace the windows in an almost 100 year old farmhouse.
But where ever you are, you look around, there are old houses, sheds and buildings bout everywhere that are falling down or in disrepair ...... that have a pane or two of glass large enough to cut replacements out of.
cheers
