Aluminum Sliding Door Lock Set

A home owner from San Antonio, TX says:
I have identified the main lock as your part # 82-002 , Sliding Door Handle Set, 6-5/8"

However, this part does not come with the other part, installed in the accompanying door, which grabs the pin (or teeth) coming from part 82-002 and locks both doors together.
The doors were installed in 1992.

The measurements of the old part are 3/4" wide by 2 3/4" long.

I think the part # for this receiving part, mentioned before, is # 89-003 . If this is the case, please confirm. However, it does not come with screws. Do you sell the screws separately.

Thanks for posting. The part you need is known as a keeper. The 82-002 handle set does come with one, actually. You can see it in its product photos.
