Thumb latch

A quick learner from Michigan says:
Hi. I have a thumb latch deadbolt handle that is missing the thumb latch. Can I just order a new thumb latch or do I have to order the while handle set? Thank you!

I'm afraid we don't carry that thumb latch by itself. I do not know anyone who does, unfortunately. We do carry the 40-057 set.
