The house was built in 1976 and the sliding door is original equipment. The door is 1" thick and the opening for the handle set is 7-3/16" x 13/16" (+-1/32).The existing set says "Woodbine Ind Ltd Japan" and the installation hole centers measure 6-5/8". It looks a lot like your 82-002 or 82-002K.
If that's your recommendation, I have two questions:
1. What's the difference between 82-002 and 82-002K?
2. Do 82-002 and 82-002K allow me to latch/unlatch the door from the inside when the key on the outside is unlocked?
If you have a set that you think is a better fit than 82-002 or 82-002K, please let me know.
Thanks for your help!

P.S. I purchased your roller set 81-005 for my other identical door last month. It's a perfect fit and the door slides more easily than it has in 25 years.
