replacement widow channel balances

Question

I have several windows where the channel balances have failed. They all look the same except are different lengths. I need one 31HD, 6 27TG, and 2 27C.

Is that enough to determine which channel balances I need?

We should be able to help, though this balance will need to be custom made. Before we begin, can you show me a clear picture of how this balances attaches to the window jamb at the top? Can you also tell me the weight of the sash for each case? The stamps you gave usually tell us that, but the first two are a little different from what is normally used on this balance and I want to confirm.
