Finaly figured out rib angle brace for NR1. I have angles for NR 2 and part of NR1 installed properly. I was able to figure out that my blue prints have the 6ZU-1-4 and 6ZU-1-3 angles mislabled on drawing. Still trying to figure out if NR 3&4 need to be modified. Im hoping not but suspect they will.
