    Panhard Rods run diagonally across between a top and bottom frame, with rose or heim joints either end, and they will prevent lateral twisting. A beefy U-joint will do the same job and is less complex.

    The top heim joints, as rendered, have lots of deflection and risk binding. At a minimum a spacer would be advisable, but it is better to mount heim joints so their rotation is in their natural lateral plane, not twisting from that.

    How do you solve the issue of pitch movement? There has to be some give somewhere?

    I was looking around and thought that maybe getting two of these to replace the threaded rods would allow for the small amount of movement needed, and also dampen a lot of the movements I am seeing... Thoughts?
