Missing or broken part inside this operator?

A quick learner from arizona says:
1. The #401 skylight operator uses the hook on the left of img0851. I found the hook fallen on the floor one day. I can put it back and it opens up the skylight but falls down easily. Do you have any idea if something is broken inside or if I am missing a spring that holds the hook in place?

2. I have another unit that uses the hook on the right side. The skylight operator still works but it the hexagonal part on the top is stripped (img0852). Do you have this part available?

This looks like the older version of our 39-551. Unfortunately, we dont have the threaded kind. It may not be made anymore. I also don't think the 39-551 works in the old version of this operator, so you may need whole new 39-405.
