window is about 20 years old and markings cannot be read. Can you help identify this replacement part? I will need both a left and right crank.

Sure, see our 39-187 and 39-188. These appear to match the arm design on your old crank operator.

I'm afraid we do not have the 39-187 and 39-188 with 4.5" long link arms. If you need that length, you would need to install the old link arms on the new balance. You can do this by drilling them out and installing them with the 62-014 rivet.
