If you do a search here on the 3D forum for Katana first flight,started by me,you will see some pics of the R/C hardware on my Edge.The servo end ball liknks are #87,and the control horns are 01B,the control horns come with two single screws and a 3" threaded rod and enough hardware to set up two horns or one double horn for pull-pull.Or you can use the 01A which only comes with one horn set up,I perfer the 01B.I would try Don's hobby Shop for these parts,my experiences with Nelson have been terrible,and Don's stocks all the Nelson products also,and will have them to you in 3 days,With Nelson who knows when you'll see them!!But that is only my experience.
