Replacement casement window operators

Existing Truth operators are 30yrs old and gears are failing. I would like to replace the two operators with new ones. They are for right-hand windows. Parts are marked Truth. The hinge arm has the number 40887 on it (see photo 2624). The main arm (long arm) has the number 40255A on the bottom. I have successfully replaced three awning operators in this home already with Truth replacements. Thank you for your help.

Thank you, Tom! It looks like the ones you identified will do the trick! I will order what I need.

Thank you also for the quick reply (Friday--> Tuesday).
