Default Rudder rodend bearing

The upper and mid rod end bearings are in and adjusted but I canít get the threads on the lower one to engage with the nutplate. Any ideas? Does it look like Iíve damaged the nutplate thread?

Are you sure the hole in the spar is opened up enough?

Sometimes nutplates shift just enough during installation to keep a screw from properly threading into them. One thing you could do is remove the nutplate and very slightly enlarge the hole for the bolt. Or try re-installing the nutplate using a bolt threaded into it to hold it in alignment, perhaps with a new nutplate.

Since that's the reasonably exposed one, just remove it, enlarge the hole slightly as Vic says and put in a new nutplate.

It's not really worth screwing around with one that is proving difficult to thread.

Just run a tap in enough to get the threads started. I had to do that on one of mine. You don't want to completely tap it and loose the locking capability in the nutplate.
