jmdaniel, the parts you want to purchase are numbers 4 and 6 only. I just looked at the Partzilla schematic, and my '14 Deluxe to confirm this. Parts 5 and 7 are already in place on your Deluxe with the backrest... they would be replaced with 4 & 6 when/if you remove the backrest.
I hope this is helpful.
Ride safe, amigo.
edit - DMAGOLDRDR just said the same. Boy is he quick!
