I'm interested to see what you find out about the K-member. The four point brace is the only other piece I haven't added to my build. Mainly because I don't know whether I'll use long tubes or not. I find it curious one never knows what they will find as far as symptoms of different assemblies or manufacturing tolerance differences.
