The number you have provided to us is leading me to some of our replacement Andersen door hardware. However, without photos showing your parts, we can't be certain we are on the same page with you. If you could reply back with some photos and measurements of the hardware in question, it would increase our chances of finding the piece(s) you need. 

Thank you! This looks very similar to the mortise that comes with our 82-037 Andersen lock kit. Look it over and let me know if you agree!

Great! I can't order it for you here, but you can place your order directly from our site at your convenience.
