Got my first build underway today, will post pics when it's done.
But, what is the best way to mark the holes for the trunions on an NDS receiver? I was thinking maybe to cut the old stubs so that they sit flat on the new one and just trace them. Will this work, or is there a better more accurate way?

You can use the old receiver to overlay as you describe.
Some folks use a stickie note to trace the hole location off the old receiver and overlay that on the new. Or
Measure carefully and drill a small pilot hole to make sure you are close. File if off center to obtain correct location
Use a blind hole finder tool
Or use the method in this post if you have a drll press wth a moveable table or right angle clamp.

On the front trunnion I usually lay the right side of the trunnion against the outside of the receiver on the left (as looking at it from the rear) and clamp it then drill the holes. I then install the trunnion in the receiver, put rivets in holes for alignment and drill the other side through the existing trunnion holes. On the rear I use the prementioned method but use a dremel instead of a file.

There's mutiple ways to do this - some ways are accurate, other ways are easy - but there's one way that is both accurate and easy - see mOondoggy's video I linked to in this thread:

Looks like thats how I'm going to do it. Will this also work for the rear trunion?
