Window Replacement Arms and seal

Hi, Lori.

Your operator looks like a good match for our 39-220B and 39-221B which are compatible with the 39-545 and 39-546 stud brackets. If you need a new cover and handle, see our 39-375 and 39-376. Look this parts over and see if they match up. 

I'm afraid we can't help with damage in your second picture, however. It looks to be a part of the window itself. You would need to contact the original manufacturer for assistance, whoever they may be. I am sorry for the inconvenience.
