Identifying the Sash Balance I need

A quick learner from New York says:

Here is what I can read off the part. 11600-17 and B-1 4719 486 This is for a 20.75 X 14 window. This is just measuring the glass. the glass has 8670 printed on it.

Also needed is the part number for 127 5732 5 38 this is for a 32.75 x 14 inch window. this also has the 11600-17 number.
I need to cross reference the parts two I have.
Please help me in ordering the correct parts, I will need two of each.

Thanks for posting. Based on your stamp of "4719" for the first balance, I'd recommend our 24-431. For the second balance, it's harder to say, but based on your sash size I think our 24-737 can work.
