I bought the later clamp fitting rack. Not impressed. The angles bored through the clamp halves did not match the angle of the roll hoops. When the clamps were tightened the sliding dowels for the quick release locked solid. Only way to make the quick release system work, leaving the clamps tight on the roll hoops, was to drill the two outer dowel holes from 8mm to 10mm. Not what you expect for an accessory costing over £1000. (Dealer wanted an extra £80 to fit it - I now understand why). I always thought Harley accessories were expensive, but at least they fit.
