Need help replacing sashes. Sash measures 18 inches and is 1/2 inch wide. Marking on metal says "1740M."

I ordered a different size last year for a different window(Oct 2018) and it worked perfectly. You are the best!

Thanks for writing in to us again, Tom! This looks like either a S351-18 or S390-18. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You will need a stamp option of 1740.
