Need assistance identifying the right channel balance.

Various pictures are attached but I'm having trouble finding something that matches exactly online. Overall it's 32" long and, as you can see from one of the pictures it's marked with a 32D and a small letter J.

This looks like our S770-32, with a stamp of 32D. Note that this balance attaches to the top of the jamb track with a screw. Let me knows if yours differs.
