Will this work?
Juice, I have a pushrod system that I used on a 60 size Sportster 15 years ago and it is still working great. What I do is to run a one-eigth dia. wood dowel through a standard pushrod housing,support it well and keep it realitivly straight. If it can't bend it can't break! This is lightweight, strong,has no radio problems,and doesn't cause trim changes because of temperature. On each end of the dowel I epoxy on a piece of perforated brass tubing with a short length of threaded rod soldered on.Use a clevis,balljoint,or whatever to make the horn and servo connection. Sporty
