The replacement parts were received and successfully installed !!
I had to use a rat-tail file to enlarge and slightly move the holes in the sliding glass door frame in order to match the holes in the lock mechanism and the larger size of the door handle screw ports.
But it all works fine now. Thanks much.

Hi Homeowner from Arvada Colorado, looks like I have the exact same sliding door as you. When you replaced the handle and mortise lock, did you have to replace the Keeper as well, or did your old keeper work fine with the new mortise lock?
Thanks,Rick from Lakewood CO
