I'm looking to replace the sliding door handle on my sliding door. The lock lever just spins and has some play in it. The lock doesn't pop out anymore something internally is broken. After looking online it appears you may sell what I need. The mortise lock inside assembly is 5 3/4 from top to bottom. I'm told my door and windows are stamped with KK? Pictures are attached. Would you have a link to the handle hardware? Until I get it apart I don't know if the actual thumb lock needs replaced as well. It does have some play in it and didn't know if the new lock mortise would clean up that play or not. Thank you
