it looks like the smaller shoes are from the bottom window and the larger (1 3/16")are for the top window.
The window weighs 24lbs. and is 43" wide but some windows are 41" wide.
The lenght of the balance housing is 43". I would probably only do the bottom windows. I found the balances all over the building, so I don't know which windows they are from.
Please let me know about how much they will cost with the small shoe and I will talk to my boss for the ok.
Thanks
Hal
