Personally i would messure the push rod linkage you have. And get some turnbuckle linkage. So you can adjust them on the fly. You can change the rod ends to whatever you want.. can go with ball ends, hollow ball ends, aluminum rod ends, nylon, what ever you want them to be. Then like
@Chubaka said. Just use a nut on the back side of the ball or bolt/screw on the nuckles or the saver...I have ball ends on push rods on my hornet. They will be switched to a 3mm turnbuckle rod. Not these but longer ones...
