I've been looking at the bikebandit fiche's again. Bonny Scram & Thrux are identical, just the America is the odd one out... So way to tell if they are sized the same, but it would make sense that the PN would be the same if they were.
Example, Cush Drive
Bonneville: 5567930-001
America: 5567931-001
Scrambo: 5567930-001
Thrux: 5567930-001
