For any softail conversion kit HW157218 or HW157318 the customer must ensure they have pipes that are below the passenger footpeg. Many models have "shotgun" pipes that are double stacked and the footpeg is inbetween this leave no room for the conversion bracket and bag.
Another issues is stacked pipe models have a special footpeg bracket that needs to be changed to a simpler single bolt mount footpeg support.
