Those are very popular and we actually have the Smoke Chrome version on our F6B.
Since you have the base model without the backrest you will need to install the Rack Mount Kit, (can also be used for the passenger backrest).

You can see from the instructions how much work this entails, most people have not had issues with this installation. I would purchase the tapered seat bolts also since you are removing the seat.
After installation of the Rack Mount kit the Rear Rack can easily be installed.
