I'm putting a set of shocks on a 4 bar rear suspension. The shocks I will be using have bushings at both ends with a mounting bolt that goes thru the bushing. Hope I made myself clear there. Question is: should the top and bottom bushings be parallel to the rear end? Shocks will be mounted vertical looking at them from the back and 10 degrees forward tilt top to bottom. My thoughts are that the shock mounting bolts can rotate as the rear end goes up and down. Or should I mount the top parallel to the rear end and bottom perpendicular to the rear end to allow for some body roll?
