Here is my only point of "misinderstanding". The LCA travels up and down perpendicular to the LCA shaft center line. So, that means the strut rod end must travel in a arc, since it is fixed to the LCA end. This is the reason for the rubber bushings. To allow "just enough" fore and aft with the strut rod at the K frame where it installs in the bushings. So now we're talking about replacing the stock strut rods with a swivel (which I want to do).
So now we have installed a swivel strut rod totally FIXED on both ends, with no bushings. So, my question now is, WHERE is the fore and aft movement NOW? Since the strut rod now is totally fixed with no bushings, it has no way to allow that small bit of fore and aft movement going through the arc. I can only assume that small amount of fore and aft movement is transferred to "whatever" LCA bushing we use and that now the LCA has that same amount of fore and aft movement. RIGHT?
