1990 Alenco window balance replacement

A quick learner from Plano, TX says:
Please help me identify my balance. I believe the top piece is 19-005 but the bottom foot is hard. It measures 1 2/16" from top spike to bottom, 1 2/26" front to back, and 1/2" width. The only markings on the sash say 2740%

Thanks for posting. It looks like your top attachment is winged, but your bottom is non-winged. Since this does not match any of our existing Series, your balance will have to be custom made.

Before we begin, though, I'll have to figure out what your bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

Please also tell me the length of the metal channel. Do not include the plastic attachments in this measurement.
A quick learner from Plano, TX says:
Yes, I see I will need a custom piece too. The length of the metal balance piece is 28" The foot is closest to the 15-001 but the top to bottom is longer at 1 1/8? not the 1". Correction I said 2/26 I meant 2/16. Thank You.

Thank you. Please take a look at the S395-28 with the 2740 stamp option.
