parts needed to fix duble pane no tilt windows

I agree, the Series 370 appears to be the best match we have for your balance. I'm not sure about the other parts, though. Please take pictures of each one and provide dimensions. That will help us find waht you need.

Thanks for the extra information. I'm afraid that these take out forks are no longer available. They were in the window to help remove the sashes. When I worked on these windows in the past I used a #8 sheet metal screw like the 33-017 in place of the missing fork. You would need to first remove the rubber stop (should look like 59-001) from the track so that you can install the screw where the fork was. After you reinstall the sash back into the track, reinstall the 59-001 stop, leaving the screw in place. The screw should not effect the operation of the sash with the rubber stop in place. If it is, just remove the screw until the next time you need to remove the sash from the window.
