Thanks, Tom. Unfortunately, there is wood trim above the operator (see attached). It appears that I will have to remove the trim to remove the operator. Right? Since I will be replacing the damaged wood casing, I guess I can just arrange to have the top piece removed to make the necessary repairs. Does it appear that part #
39-031 Entry Gard Dual Arm Operator is the correct replacement part???
Thanks again for your assistance.
