The G Hinge.
Panty lines are a thing of the past with this nearly invisible seat hinge. Dont weld on that frame like I did..... simple hinge that bolts on to those funny little holes in your Rigid Panhead or Knucklehead frame. Fits a little higher on Knuckle frames due to geometry of original castings. Nickel plated steel, includes bolts to mount. Goes really nice with a Butts seat.
