Two small crank out windows on both sides of bay window. Haven't been used in over a decade. Need to replacements. Stamped number on one arm is L30841, r other arm is stamped R30842. Pictures attached with measurements on tape ruler. Can you assist?

Thanks for posting. I believe you have the 39-035 and 39-036 Dyad Operators. Please compare with your old hardware and let me know if you concur. For new covers and handles, see the 39-114L and 39-107 sold separately.

Thanks for the reply. My concern with your recommendation is the middle link arm coming off the gear is straight on the new part and not angled like in the picture. Wouldn't that matter?

No, that won't matter. Your operator is an older version of our part. TRUTH has since changed that detail but it still functions in all the same applications.
