I did it. You need to find a set of duel disk lowers. then you will need a axle that will fit the lowers (cause yours wont). then you need to change the bearings in your wheel to fit the axle oh...and new spacers to fit the axle. All this hinges on the fact that your tubes are 39mm...mine were 05 FXD. I think your 06 bob is 41 or 49 mm in which case you will need triple trees and tubes (basiclly a hole front end) At that point you may open up a hole new can of worms with your neck berings,cup fitment in which case....time to buy a custom front end for 1000 bucks.
