Also, is it necessary to replace the pivot lock shoes? They appear to be OK, and I couldn't find one that looks like mine. Please take a look at the pics and help me order the right stuff. Thanks!
UNIQUE 27-D-40 Channel Balance Questions

I have what I believe is a Series 770 which measures 28" long. The only stamp on it is UNIQUE 27-D-40. Should I choose option 28D when ordering? The window weighs 25 pounds.

Hello,
If pivot shoe is in working order, there is no need to replace.
28" Series 770 with 27D stamp will carry a window sash weight range of 23 through 28 pounds. This will work well for a 25 pound sash.
This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
