I have two windows needing replacement parts for R split arm crank mechanism probably installed in 1988 when the house was built. The only id seen is the logo Truth and a number 20810. Can you please help me find two of these parts?

Hello, thank you for posting,

Please start by reviewing the style and dimensions of the 39-031 and 39-032 operators to confirm a good fit. If a new cover and handle are needed, review the 39-107 and 39-114L. Let us know what you think and if you have any additional questions.
