Tango

You have a good looking set up, will it hold up i am not sure but think it may work loose with time. But your ideal is a good one. I took a grinder and grind off the brass arm and put a nose wheel steering arm on mind, once i got it set i drill a dimple in the rod so the set screw could have a place to set. put lock tight on set screw and its stay in place. this is just another ideal in case yours dont work out for you;

GOOD LUCK
