Here is a pic of the disassembled part. Do you have a better guess as to the part #?

I see you're showing us a complete coil spring system. It looks like you will need our 15-180 coil balance shoe, 15-181 double support clip, and 15-182 balance bushing. This pieces can be used with the Series 190 coil spring. Look over each part to confirm whether or not they match up to your original pieces.There should be some sort of number or marking stamped on the spring itself to determine which strength coil to use. If there are no numbers on the spring, please get back to us with the exact weight of your sash.
