Looking for Replacement Part for Milgard Sliding Door Handle

Looking for replacement part to replace middle piece for milgard sliding door handle for a patio door. One of the screws no longer holds so when you pull on the handle, one of the screws is loose so when you pull door it is now supported by one screw instead of two. the middle part i am trying to replace has worn out and does not hold the screw in.

Part says it is made in new Zealand. This is the middle part that gets sandwiched between the other door handle parts and sits in the middle.

Pictures for door handle online seems similar to milgard sliding door handle set classic style D, but i have not been able to find the exact part name or part number to replace.

If you carry this replacement part, please let me know so i can order online.

Thank you.
