I have those exact same instructions with the kit. The cross girder (#9) has to be bolted with screw #10, washer #11 and nut #12. The problem is that I do not have any holes in my rear fender for the screws. I'll have to drill the rear fender for those. Then I must find a way to bolt my license plate to this cross girder.
I can't remember if I had to drill these two holes or not (as you can see I cut that ugly snow shovel per idea I've seen on a thread in the forum to have a home made fender eliminator).
The way I did it was to take off the license plate, install the side carriers to the foot pegs and grab handle, then connect the cross bar to the side carriers with the TwistedTh. Provided quick connect. After that I figure it out what needs to be done to install the license plate.
I used the original license plate bracket. Moved it up and used some fender washers for added support in the plastic. Not the best picture but shows what I did. Also shows the small storage box behind the plate that I keep the registration and insurance info.
As you can see, there's no predrilled holes in the fender to attach the cross bar. Also, the slots in the bar are too short to use the original license plate bracket. The slots are also too short to mount my license plate in it's original holes.
I see your problem now, the Canada plates are longer that the USA ones... Good job
