 It just has to be accurate, placed properly and to where the gauge body won't move. \\

 The probe on the indicator has to be vertical to and inline with the lifter (or cam lobe) to give accurate readings. \\
+Also to keep from bending the probe as the lifter rises. \\
 It can be placed in the center or on the outside lip of the lifter. \\

 |If made carefully, there is no need for a set screw on the nylon bushing. It's either the slip fit, chamfer on the inside rear of the hole from the drill bit, trapped air \\ when the bushing is installed, composition of the nylon or a combination of these things  that holds the bushing firm when pushed onto the pinion shaft.
