Depends on which rod ends you're using, Kurt. I usually measure the width of the rod end, then make a couple of sleeves the same width out of tubing and use them as spacers to locate the brackets.... With heim joints, I fit the brackets just snug on the joint, with the poly ends, I like about .020 clearance between the poly bushing and the bracket.....just .020" total, not .020 on either side of it.... I like to keep the poly ones a bit loose to allow the rear end to move laterally a bit when cornering and not put a lot of stress on the rod end.....Heims can be tight as by design they will allow lateral movement and not stress the joint.....
