This is a nice mount that goes with the Drag Specialties oil pressure gauge. I mounted mine on a 1990 Heritage Softail Evolution motor. I did add a plastic grommet to mine that did not come with the kit. As most of you know the Evolution motor can "grow" almost an eighth of an inch from sitting cold up to when its running hot. The retaining bracket has a slip fit on this mount to allow for this heat expansion and contraction. I did not need another rattle on this bike (seems like everything rattles on this bike) so a slipped the grommet in the mounting bracket after drilling it out a bit larger. No rattle and its still a slip fit. And I can see the oil pressure wile ridding unlike if the gauge was just mounted on the block with out this mount.
