My measurement on the side that should be 1/2" is actually 3/8"
Do I have the correct item number (see pic of your order page) for my replacement piece?
How long is the glazing bead? I have a 8/9 foot window.
What is general delivery time after order?

This looks awfully close to our 55-303. Do you think it could fit?
