Hello. I have a double hung vinyl window manufactured by Amerimax Windows. The window has two broken coil balances. I was able to remove my coil balance by using your "cut out method" shown in the video on your web site. I believe the replacement part I will need is a 15-177 and a Series 152 coil balance. My coil has a D stamped on it (see attached photo). Does that indicate what lb series coil balance I will need to order for my window?
Thank you,
Jim
