You know, you may have saved yourself from having to install a rudder stop modification as I did. I had set my angles prior to cover as well. Then, after covering, the fabric ate up that gap between the rudder and the vertical tail. To add the gap back in you have to spin the rod end bearing out a bit further. This increased the swing of the rudder since it was now slightly farther from the rudder stop. I had to drill and tap a hole in the flange on the rudder so I could install a couple of AN3 bolts and jam nuts so that I could adjust the swing of the rudder. So, if your swing is too great there is always a way out.
