adjustment of the torsion bar tension screws, their length?
 

Hello everyone,
I look at my tension adjustment screws for the tension bars on my FX4 and I suspect that it has already been done before, they are not even the same length. Does anyone know how long they were when they left the factory? My FX4 has had no problems, the rear blades are not even used so I want to put my adjustments back to the original. Can you help me find this measurement? Thanks for the help .Gervais.
