I have 2 different size windows at the moment that I would like ballasts for.
I have not found the numbers on line.
one window has both a 11600-17 and 11600-3 its a 37.5 x 24 J39-519 10-87
window.

The other is a 62x40 and it is a P78 12#31 1-86 I assume the last 10-87 and 1-86 are manufacture years.

Turns out , I also need the material in the groove that helps the window seal and glide. See pic.

For your balance stamped "519," I recommend the 24-531. For the balance stamped 12#31, I recommend the 24-1231, perhaps unsurprisingly.

I'm not sure about that seal. Can you remove an undamaged sample and show me a clear view of its end profile?

I will have to remove the window again.
It's the seal that slides on the thin protrusion. Its what guides the window up and down.
It's a slippery type of material, with a foam interior.

That sounds like just about every weatherstripping there is. We'll definitely need to see the end profile. The video below will clarify for you exactly what we need.
