Searching for replace alum sliding door latch from 196

have 1960s era aluminum sliding glass doors. Looking for the latch and cylinder assembly that is inserted inside the door because the latch hook (the end that hooks over the keeper on the frame jamb) broke off. The alum door is approx 1 1/8" thick, and the cylinder hole where the cylinder inserts into the door is 3/4" diameter, and the overall cylinder trim is 7/8" diameter. The cylinder is keyed on the outer side of the door. I believe the thumb latch and hook end were one continuous piece. The L shaped jamb keeper is 5/8" wide x 1 1/4" high. The door handle plate is 2"w x 5 1/4"h. Since the hook end broke off inside the door, I do not have a photo of it. Thanks for your help, Tom H
I would like to get 6 of these units.

I am afraid we do not have a replacement for this handle set nor its accessories. Our best option for you would be to see if you could replace this handle set with a surface mount type like our 82-005. This handle set has the key lock built into the inside pull. It has a hole spacing of 4-15/16", so bear in mind you may need to drill new holes to install it. Let me know if you have further questions.
