I have a broken sash channel balance I need to replace. This from mid-1980s gapco window. What would be a correct part?

Thanks for reaching out to us! I'm afraid we can't be certain since your balance's bottom shoe is broken but start by taking a look at the S380-35 or S385-35 with the 3440 stamp option. The Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" deep shoe. You'll have to measure an undamaged shoe as shown below to determine the best match.
Please let us know if you have any questions!
